commit 97b5046ccd87c8b674d16b16f561821cf8345c26
Author: Eric Blake <address@hidden>
Date:   Thu Oct 15 07:00:38 2009 -0600

    Improve INSTALL wording.
    
    * doc/install.texi (Basic Installation): Clarify installcheck
    behavior.
    (Installation Names): Mention that --prefix only overrides
    directory locations not specified on the command line.  Prefer
    /alternate/directory over /path/to.  Remove a sentence targeted to
    the developer, not the user.
    * THANKS: Update.
    Suggested by Alfred M. Szmidt.
