README for hardlink
=====================
hardlink is a tool which replaces multiple copies of a file with hardlinks.
Inspiration came from http://code.google.com/p/hardlinkpy/, but no code has
been used.

This version was originally written in Python as well, but performance issues
on large data sets caused it to be rewritten in C.

Installation
------------
To install hardlink into /usr, run make install.

 * DESTDIR - May be set to another root system (useful for packaging)
 * PREFIX  - Normally usr, may be changed to usr/local
 * MANDIR  - Normally $(PREFIX)/share/man (some systems may use $(PREFIX)/man)
 * BINDIR  - Normally $(PREFIX)/bin

Differences to hardlinkpy
-------------------------
For users of hardlinkpy, several things are different. One of the most
important changes is the renaming of all --foo-ignore arguments to
--ignore-foo ones. This is more similar to the naming of options in GNU
programs.

* --timestamp-ignore has been renamed to --ignore-time
* --owner-ignore has been renamed to --ignore-owner
* --rights-ignore has been renamed to --ignore-mode
* --filenames-equal has been renamed to --respect-name

The option --reverse has been renamed to --minimize. The option --max has
been renamed to --maximize.

At the moment, output is different. This may change at a later point.
