It can be useful to add comments in the 'Depends-on' section of a module
description. This change lets gnulib-tool recognize these comments.
2011-06-13 Bruno Haible <br...@clisp.org>
gnulib-tool: Allow comments in the 'Depends-on' section.
* doc/gnulib.texi (Module description): Mention comment syntax in the
Depends-on section.
* gnulib-tool (func_get_dependencies): Filter out comment lines.

@item configure.ac-early
This field contains @file{configure.ac} stuff (Autoconf macro invocations and
shell statements) that are logically placed early in the @file{configure.ac}
