INSTALLATION
will be substituted with installation directory.
Normally INSTALLATION/bin/hg
but you could specify another name
such as INSTALLATION/my-mercurial.py
or even look for Mercurial
in the default path (leaving installation directory blank) using just hg
.
If you are configuring per-node tool home locations,
you may leave the installation directory undefined on some nodes,
in which case just hg
(i.e., from $PATH
) is used.
