+.SH DESCRIPTION
+.I Diffdir
+does diffs on directories by sorting the contents of the directories by
+name and then running diffs on text files which are different.
+Object files which differ and files which appear in only one directory
+are also listed.
+.PP
+The
+.B \-h
+option causes diffdir to paginate its output, and to summarize
+binary differences and files in only one place at the end of the diff.
+Each individual diff is run through an appropriate
+.I pr.
+.PP
+The
+.B \-s
+option causes files which are the same to be reported;
+normally they are omitted.
+The
+.B \-e
+option causes the output to be a
+.IR csh (1)
+script containing
+.IR ed (1)
+commands to change the first directory to the second.
+The
+.B \-v
+option causes slightly more verbose output.

+.SH BUGS
+Program needs more work, i.e. it could be made hierarchical.
+.PP
+Scripts made by
+.I diffdir
+.B \-e
+contain lines with only a `.'.
+If the resulting file is mailed,
+.I mail (1)
+will throw away the rest of the file.
+The file must be right shifted by a tab stop to avoid this.
