Add manpage files: xxhsum.1 and xxhsum.1.md You can generate xxhsum.1 by the following procedure: ``` sudo apt-get install -y ruby-ronn # make man generates xxhsum.1 from xxhsum.1.md # make man # edit xxhsum.1.md here # # auto preview for development make preview-man ``` `Makefile` has the following tricky part: ``` xxhsum.1: xxhsum.1.md cat $^ | $(MD2ROFF) $(MD2ROFF_FLAGS) | sed -n '/^\.\\\".*/!p' > $@ ``` Last `sed` command removes `ronn`'s comment lines (`ronn`'s version, author, URL). It doesn't mean disrespect for `ronn`. We need this removal because we must ignore `ronn`'s version to minimize diff.

\fBxxhsum\fR supports a command line syntax similar but not identical to md5sum(1)\. Differences are: \fBxxhsum\fR doesn\'t have text/binary mode switch (\fB\-b\fR, \fB\-t\fR); \fBxxhsum\fR always treats file as binary file; \fBxxhsum\fR has hash bit width switch (\fB\-H\fR);
