add guile-tools?

[thi]

below is a quick and dirty wrapper that i use personally.  it might be
useful to be included in the guile distribution and installed as
$bindir/guile-tools, so if nobody objects, i will spiff it up (convert
to use configure-substituted vars, add --help and --version handling,
add comments, maybe rewrite in scheme, etc) and check it in.

on the other hand, i can see people not liking the further pollution of
$bindir or having other objections, in which case i would just append it
as a "serving suggestion" in scripts/README...

example usages: guile-tools --version
                guile-tools --help
                guile-tools --help display-commentary
                guile-tools display-commentary *.scm
                guile-tools punify *.scm

please let me know what you think.
