-# Convenience script for regenerating all autogeneratable files that are
-# omitted from the version control repository. In particular, this script
-# also regenerates all aclocal.m4, config.h.in, Makefile.in, configure files
-# with new versions of autoconf or automake.
-#
-# This script requires autoconf-2.62..2.69 and automake-1.11.1..1.12 in the
-# PATH.
-# It also requires either
-#   - the git program in the PATH and an internet connection, or
-#   - the GNULIB_TOOL environment variable pointing to the gnulib-tool script
-#     in a gnulib checkout
-# The former method is tried first and if it fails, fallback to the
-# latter.  When git is used, the GNULIB_SRCDIR environment variable is
-# also checked as a reference of gnulib checkout.
-
-# It also requires
-#   - the bison program,
-#   - the gperf program,
-#   - the groff program,
-#   - the makeinfo program from the texinfo package,
-#   - perl.

-# Usage: ./autogen.sh [--quick] [--skip-gnulib]
+# This script populates the build infrastructure in the source tree
+# checked-out from VCS.  To regenerate other materials, such as PO
+# files and manual pages, use update-po.sh.
+#
+# This script requires:
+#   - Autoconf
+#   - Automake
+#   - Wget
+#   - Git
+#
+# By default, it fetches Gnulib as a git submodule.  If you already
+# have a local copy of Gnulib, you can avoid extra network traffic by
+# setting the GNULIB_SRCDIR environment variable pointing to the path.
+#
+# In addition, it fetches the archive.dir.tar.gz file, which contains
+# data files used by the autopoint program.  If you already have the
+# file, place it under gettext-tools/misc, before running this script.
