+# gram  on compressed files.  All options specified are passed
+# directly to cmp or diff.  If only 1 file is specified,  then
+# the  files  compared  are file1 and an uncompressed file1.gz.
+# If two files are specified, then they are  uncompressed  (if
+# necessary) and fed to cmp or diff.  The exit status from cmp
+# or diff is preserved.
