+# SYNOPSIS
+#
+# AX_GENERATE_CHANGELOG()
+#
+# DESCRIPTION
+#
+# Builds a rule for generating a ChangeLog file from version control
+# system commit messages. Currently, the only supported VCS is git, but
+# support for others could be added in future.
+#
+# Defines GENERATE_CHANGELOG_RULES which should be substituted in your
+# Makefile.
+#
+# Usage example:
+#
+# configure.ac:
+#
+# AX_GENERATE_CHANGELOG
+#
+# Makefile.am:
+#
+# @GENERATE_CHANGELOG_RULES@
+# CHANGELOG_START = 0.2.3^
+# dist-hook: dist-ChangeLog
+#
+# ChangeLog (stub committed to VCS):
+#
+# The ChangeLog is auto-generated when releasing.
+# If you are seeing this, use 'git log' for a detailed list of changes.
+#
+# This results in a "dist-ChangeLog" rule being added to the Makefile.
+# When run, "dist-ChangeLog" will generate a ChangeLog in the
+# $(top_distdir), using $(CHANGELOG_GIT_FLAGS) to format the output from
+# "git log" being run in $(CHANGELOG_GIT_DIR).
+#
+# Unless Automake is initialised with the 'foreign' option, a dummy
+# ChangeLog file must be committed to VCS in $(top_srcdir), containing the
+# text above (for example). It will be substituted by the automatically
+# generated ChangeLog during "make dist".
