Though mercurial-server is currently targeted at Debian-based systems such
as Ubuntu, other users have reported success getting it running on other
Unix-based systems such as Red Hat. Running it on a non-Unix system such as
Windows is not supported. You will need root privileges to install it. 

The best way to install mercurial-server is using your package management
system - there are pre-built .deb files on the website. However, there is
some provision for installing it directly. On Debian based systems such as
Ubuntu, use the command

    sudo make setup-adduser

On Red Hat and possibly other variants of Unix, try

    sudo make setup-useradd

See doc/manual.docbook for the rest of the documentation.
