- /bin/sh or the shell \$CONFIG_SHELL
- --no-bootstrap-sync do not check whether bootstrap is out of sync
- --copy copy files instead of creating symbolic links
- --force attempt to bootstrap even if the sources seem
- not to have been checked out
- --no-git do not use git to update gnulib. Requires that
- --gnulib-srcdir point to a correct gnulib snapshot
- --skip-po do not download po files

-If the file $me.conf exists in the same directory as this script, its

-
-Gnulib sources can be fetched in various ways:
-
- * If this package is in a git repository with a 'gnulib' submodule
- configured, then that submodule is initialized and updated and sources
- are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
- --gnulib-srcdir) and is a git repository, then it is used as a reference.
-
- * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
- then sources are fetched from that local directory. If it is a git
- repository and \$GNULIB_REVISION is set, then that revision is checked
- out.
-
- * Otherwise, if this package is in a git repository with a 'gnulib'
- submodule configured, then that submodule is initialized and updated and
- sources are fetched from there.
-
- * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
- cloned into that directory using git from \$GNULIB_URL, defaulting to
- $default_gnulib_url.
- If \$GNULIB_REVISION is set, then that revision is checked out.
-
- * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
- used. If it is a git repository and \$GNULIB_REVISION is set, then that
- revision is checked out.
-
-If you maintain a package and want to pin a particular revision of the
-Gnulib sources that has been tested with your package, then there are two
-possible approaches: either configure a 'gnulib' submodule with the
-appropriate revision, or set \$GNULIB_REVISION (and if necessary
-\$GNULIB_URL) in $me.conf.
-
-Running without arguments will suffice in most cases.

+ GNULIB_SRCDIR Specifies the local directory where gnulib
+ sources reside. Use this if you already
+ have gnulib sources on your machine, and
+ you want to use these sources.
+ GNULIB_REFDIR Specifies the local directory where a gnulib
+ repository (with a .git subdirectory) resides.
+ Use this if you already have gnulib sources
+ and history on your machine, and do not want
+ to waste your bandwidth downloading them again.
+ GNULIB_URL Cloneable URL of the gnulib repository.
+
+Options:
+ --bootstrap-sync if this bootstrap script is not identical to
+ the version in the local gnulib sources,
+ update this script, and then restart it with
+ /bin/sh or the shell \$CONFIG_SHELL
+ --no-bootstrap-sync do not check whether bootstrap is out of sync
+ --force attempt to bootstrap even if the sources seem
+ not to have been checked out
+ --no-git do not use git to update gnulib. Requires that
+ \$GNULIB_SRCDIR or the --gnulib-srcdir option
+ points to a gnulib repository with the correct
+ revision
+ --skip-po do not download po files

+If the file bootstrap.conf exists in the same directory as this script, its
+contents are read as shell variables to configure the bootstrap.
+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+ environment variable or via the --gnulib-srcdir option), then sources
+ are fetched from that local directory. If it is a git repository and
+ the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+ submodule configured, then that submodule is initialized and updated
+ and sources are fetched from there. If GNULIB_REFDIR is set (either
+ as an environment variable or via the --gnulib-refdir option) and is
+ a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+ are cloned into that directory using git from \$GNULIB_URL, defaulting
+ to $default_gnulib_url.
+ If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+ used. If it is a git repository and the configuration variable
+ GNULIB_REVISION is set in bootstrap.conf, then that revision is
+ checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
+
+Running without arguments will suffice in most cases.

- /bin/sh or the shell \$CONFIG_SHELL
- --no-bootstrap-sync do not check whether bootstrap is out of sync
- --copy copy files instead of creating symbolic links
- --force attempt to bootstrap even if the sources seem
- not to have been checked out
- --no-git do not use git to update gnulib. Requires that

- --skip-po do not download po files

-
-Gnulib sources can be fetched in various ways:
-
- * If this package is in a git repository with a 'gnulib' submodule
- configured, then that submodule is initialized and updated and sources
- are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
- --gnulib-srcdir) and is a git repository, then it is used as a reference.
-
- * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
- then sources are fetched from that local directory. If it is a git
- repository and \$GNULIB_REVISION is set, then that revision is checked
- out.
-
- * Otherwise, if this package is in a git repository with a 'gnulib'
- submodule configured, then that submodule is initialized and updated and
- sources are fetched from there.
-
- * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
- cloned into that directory using git from \$GNULIB_URL, defaulting to
- $default_gnulib_url.
- If \$GNULIB_REVISION is set, then that revision is checked out.
-
- * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
- used. If it is a git repository and \$GNULIB_REVISION is set, then that
- revision is checked out.
-
-If you maintain a package and want to pin a particular revision of the
-Gnulib sources that has been tested with your package, then there are two
-possible approaches: either configure a 'gnulib' submodule with the
-appropriate revision, or set \$GNULIB_REVISION (and if necessary
-\$GNULIB_URL) in $me.conf.
-
-Running without arguments will suffice in most cases.

+Optional environment variables:
+ GNULIB_SRCDIR Specifies the local directory where gnulib
+ sources reside. Use this if you already
+ have gnulib sources on your machine, and
+ you want to use these sources.
+ GNULIB_REFDIR Specifies the local directory where a gnulib
+ repository (with a .git subdirectory) resides.
+ Use this if you already have gnulib sources
+ and history on your machine, and do not want
+ to waste your bandwidth downloading them again.
+ GNULIB_URL Cloneable URL of the gnulib repository.
+
+Options:
+ --bootstrap-sync if this bootstrap script is not identical to
+ the version in the local gnulib sources,
+ update this script, and then restart it with
+ /bin/sh or the shell \$CONFIG_SHELL
+ --no-bootstrap-sync do not check whether bootstrap is out of sync
+ --force attempt to bootstrap even if the sources seem
+ not to have been checked out
+ --no-git do not use git to update gnulib. Requires that
+ \$GNULIB_SRCDIR or the --gnulib-srcdir option
+ points to a gnulib repository with the correct
+ revision
+ --skip-po do not download po files

+If the file bootstrap.conf exists in the same directory as this script, its
+contents are read as shell variables to configure the bootstrap.
+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+ environment variable or via the --gnulib-srcdir option), then sources
+ are fetched from that local directory. If it is a git repository and
+ the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+ submodule configured, then that submodule is initialized and updated
+ and sources are fetched from there. If GNULIB_REFDIR is set (either
+ as an environment variable or via the --gnulib-refdir option) and is
+ a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+ are cloned into that directory using git from \$GNULIB_URL, defaulting
+ to $default_gnulib_url.
+ If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+ used. If it is a git repository and the configuration variable
+ GNULIB_REVISION is set in bootstrap.conf, then that revision is
+ checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
+
+Running without arguments will suffice in most cases.

- /bin/sh or the shell \$CONFIG_SHELL
- --no-bootstrap-sync do not check whether bootstrap is out of sync
- --copy copy files instead of creating symbolic links
- --force attempt to bootstrap even if the sources seem
- not to have been checked out
- --no-git do not use git to update gnulib. Requires that
- --gnulib-srcdir point to a correct gnulib snapshot
- --skip-po do not download po files

-
-Gnulib sources can be fetched in various ways:
-
- * If this package is in a git repository with a 'gnulib' submodule
- configured, then that submodule is initialized and updated and sources
- are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
- --gnulib-srcdir) and is a git repository, then it is used as a reference.
-
- * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
- then sources are fetched from that local directory. If it is a git
- repository and \$GNULIB_REVISION is set, then that revision is checked
- out.
-
- * Otherwise, if this package is in a git repository with a 'gnulib'
- submodule configured, then that submodule is initialized and updated and
- sources are fetched from there.
-
- * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
- cloned into that directory using git from \$GNULIB_URL, defaulting to
- $default_gnulib_url.
- If \$GNULIB_REVISION is set, then that revision is checked out.
-
- * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
- used. If it is a git repository and \$GNULIB_REVISION is set, then that
- revision is checked out.
-
-If you maintain a package and want to pin a particular revision of the
-Gnulib sources that has been tested with your package, then there are two
-possible approaches: either configure a 'gnulib' submodule with the
-appropriate revision, or set \$GNULIB_REVISION (and if necessary
-\$GNULIB_URL) in $me.conf.
-
-Running without arguments will suffice in most cases.

+
+Optional environment variables:
+ GNULIB_SRCDIR Specifies the local directory where gnulib
+ sources reside. Use this if you already
+ have gnulib sources on your machine, and
+ you want to use these sources.
+ GNULIB_REFDIR Specifies the local directory where a gnulib
+ repository (with a .git subdirectory) resides.
+ Use this if you already have gnulib sources
+ and history on your machine, and do not want
+ to waste your bandwidth downloading them again.
+ GNULIB_URL Cloneable URL of the gnulib repository.
+
+Options:
+ --bootstrap-sync if this bootstrap script is not identical to
+ the version in the local gnulib sources,
+ update this script, and then restart it with
+ /bin/sh or the shell \$CONFIG_SHELL
+ --no-bootstrap-sync do not check whether bootstrap is out of sync
+ --force attempt to bootstrap even if the sources seem
+ not to have been checked out
+ --no-git do not use git to update gnulib. Requires that
+ \$GNULIB_SRCDIR or the --gnulib-srcdir option
+ points to a gnulib repository with the correct
+ revision
+ --skip-po do not download po files

+If the file bootstrap.conf exists in the same directory as this script, its
+contents are read as shell variables to configure the bootstrap.
+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+ environment variable or via the --gnulib-srcdir option), then sources
+ are fetched from that local directory. If it is a git repository and
+ the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+ submodule configured, then that submodule is initialized and updated
+ and sources are fetched from there. If GNULIB_REFDIR is set (either
+ as an environment variable or via the --gnulib-refdir option) and is
+ a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+ are cloned into that directory using git from \$GNULIB_URL, defaulting
+ to $default_gnulib_url.
+ If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+ used. If it is a git repository and the configuration variable
+ GNULIB_REVISION is set in bootstrap.conf, then that revision is
+ checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
+
+Running without arguments will suffice in most cases.

- --copy copy files instead of creating symbolic links
- --force attempt to bootstrap even if the sources seem
- not to have been checked out
- --no-git do not use git to update gnulib. Requires that

-
-Gnulib sources can be fetched in various ways:
-
- * If this package is in a git repository with a 'gnulib' submodule
- configured, then that submodule is initialized and updated and sources
- are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
- --gnulib-srcdir) and is a git repository, then it is used as a reference.
-
- * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
- then sources are fetched from that local directory. If it is a git
- repository and \$GNULIB_REVISION is set, then that revision is checked
- out.
-
- * Otherwise, if this package is in a git repository with a 'gnulib'
- submodule configured, then that submodule is initialized and updated and
- sources are fetched from there.
-
- * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
- cloned into that directory using git from \$GNULIB_URL, defaulting to
- $default_gnulib_url.
- If \$GNULIB_REVISION is set, then that revision is checked out.
-
- * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
- used. If it is a git repository and \$GNULIB_REVISION is set, then that
- revision is checked out.
-
-If you maintain a package and want to pin a particular revision of the
-Gnulib sources that has been tested with your package, then there are two
-possible approaches: either configure a 'gnulib' submodule with the
-appropriate revision, or set \$GNULIB_REVISION (and if necessary
-\$GNULIB_URL) in $me.conf.
-
-Running without arguments will suffice in most cases.

+ sources reside. Use this if you already
+ have gnulib sources on your machine, and
+ you want to use these sources.
+ GNULIB_REFDIR Specifies the local directory where a gnulib
+ repository (with a .git subdirectory) resides.
+ Use this if you already have gnulib sources
+ and history on your machine, and do not want
+ to waste your bandwidth downloading them again.
+ GNULIB_URL Cloneable URL of the gnulib repository.
+
+Options:
+ --bootstrap-sync if this bootstrap script is not identical to
+ the version in the local gnulib sources,
+ update this script, and then restart it with
+ /bin/sh or the shell \$CONFIG_SHELL
+ --no-bootstrap-sync do not check whether bootstrap is out of sync
+ --force attempt to bootstrap even if the sources seem
+ not to have been checked out
+ --no-git do not use git to update gnulib. Requires that
+ \$GNULIB_SRCDIR or the --gnulib-srcdir option

+ revision
+ --skip-po do not download po files

+If the file bootstrap.conf exists in the same directory as this script, its
+contents are read as shell variables to configure the bootstrap.
+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+ environment variable or via the --gnulib-srcdir option), then sources
+ are fetched from that local directory. If it is a git repository and
+ the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+ submodule configured, then that submodule is initialized and updated
+ and sources are fetched from there. If GNULIB_REFDIR is set (either
+ as an environment variable or via the --gnulib-refdir option) and is
+ a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+ are cloned into that directory using git from \$GNULIB_URL, defaulting
+ to $default_gnulib_url.
+ If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+ used. If it is a git repository and the configuration variable
+ GNULIB_REVISION is set in bootstrap.conf, then that revision is
+ checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
+
+Running without arguments will suffice in most cases.

- --no-bootstrap-sync do not check whether bootstrap is out of sync
- --copy copy files instead of creating symbolic links
- --force attempt to bootstrap even if the sources seem
- not to have been checked out
- --no-git do not use git to update gnulib. Requires that

-
-Gnulib sources can be fetched in various ways:
-
- * If this package is in a git repository with a 'gnulib' submodule
- configured, then that submodule is initialized and updated and sources
- are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
- --gnulib-srcdir) and is a git repository, then it is used as a reference.
-
- * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
- then sources are fetched from that local directory. If it is a git
- repository and \$GNULIB_REVISION is set, then that revision is checked
- out.
-
- * Otherwise, if this package is in a git repository with a 'gnulib'
- submodule configured, then that submodule is initialized and updated and
- sources are fetched from there.
-
- * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
- cloned into that directory using git from \$GNULIB_URL, defaulting to
- $default_gnulib_url.
- If \$GNULIB_REVISION is set, then that revision is checked out.
-
- * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
- used. If it is a git repository and \$GNULIB_REVISION is set, then that
- revision is checked out.
-
-If you maintain a package and want to pin a particular revision of the
-Gnulib sources that has been tested with your package, then there are two
-possible approaches: either configure a 'gnulib' submodule with the
-appropriate revision, or set \$GNULIB_REVISION (and if necessary
-\$GNULIB_URL) in $me.conf.
-
-Running without arguments will suffice in most cases.

+ GNULIB_URL Cloneable URL of the gnulib repository.

+ --no-git do not use git to update gnulib. Requires that

+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+ environment variable or via the --gnulib-srcdir option), then sources
+ are fetched from that local directory. If it is a git repository and
+ the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+ submodule configured, then that submodule is initialized and updated
+ and sources are fetched from there. If GNULIB_REFDIR is set (either
+ as an environment variable or via the --gnulib-refdir option) and is
+ a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+ are cloned into that directory using git from \$GNULIB_URL, defaulting
+ to $default_gnulib_url.
+ If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+ then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+ used. If it is a git repository and the configuration variable
+ GNULIB_REVISION is set in bootstrap.conf, then that revision is
+ checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
