+Usage: $ME [OPTIONS] [ARGS]
+
+Convert git log output to ChangeLog format.  If present, any ARGS
+are passed to "git log".  To avoid ARGS being parsed as options to
+$ME, they may be preceded by '--'.
+
+OPTIONS:
+
+   --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+                  makes a change to SHA1's commit log text or metadata.
+   --append-dot append a dot to the first line of each commit message if
+                  there is no other punctuation or blank at the end.
+   --no-cluster never cluster commit messages under the same date/author
+                  header; the default is to cluster adjacent commit messages
+                  if their headers are the same and neither commit message
+                  contains multiple paragraphs.
+   --srcdir=DIR the root of the source tree, from which the .git/
+                  directory can be derived.
+   --since=DATE convert only the logs since DATE;
+                  the default is to convert all log entries.
+   --format=FMT set format string for commit subject and body;
+                  see 'man git-log' for the list of format metacharacters;
+                  the default is '%s%n%b%n'
+   --strip-tab  remove one additional leading TAB from commit message lines.
+   --strip-cherry-pick  remove data inserted by "git cherry-pick";
+                  this includes the "cherry picked from commit ..." line,
+                  and the possible final "Conflicts:" paragraph.
+   --help       display this help and exit
+   --version    output version information and exit
+
+EXAMPLE:
+
+  $ME --since=2008-01-01 > ChangeLog
+  $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line.  They are not copied to the output.
+
+  Copyright-paperwork-exempt: Yes
+    Append the "(tiny change)" notation to the usual "date name email"
+    ChangeLog header to mark a change that does not require a copyright
+    assignment.
+  Co-authored-by: Joe User <user\@example.com>
+    List the specified name and email address on a second
+    ChangeLog header, denoting a co-author.
+  Signed-off-by: Joe User <user\@example.com>
+    These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code.  Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:
