+======================
+
+NAME
+----
+git-cvsexportcommit - Export a commit to a CVS checkout
+
+
+SYNOPSIS
+--------
+git-cvsapplycommmit.perl 
+                        [ -h ] [ -v ] [ -c ] [ -p ] [PARENTCOMMIT] COMMITID 
+
+
+DESCRIPTION
+-----------
+Exports a commit from GIT to a CVS checkout, making it easier
+to merge patches from a git repository into a CVS repository. 
+
+Execute it from the root of the CVS working copy. GIT_DIR must be defined. 
+
+It does its best to do the safe thing, it will check that the files are 
+unchanged and up to date in the CVS checkout, and it will not autocommit 
+by default.
+
+Supports file additions, removals, and commits that affect binary files.
+
+If the commit is a merge commit, you must tell git-cvsapplycommit what parent
+should the changeset be done against. 
+
+OPTIONS
+-------
+
+-c::
+	Commit automatically if the patch applied cleanly. It will not
+	commit if any hunks fail to apply or there were other problems.
+
+-p::
+	Be pedantic (paranoid) when applying patches. Invokes patch with 
+	--fuzz=0
+
+-v::
+	Verbose.
