hgexternals is a Mercurial extension that simulates in some ways Subversion's externals features.
To enable the "hgexternals" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your hgrc, like this:
[extensions] hgexternals =
For help using hgexternals, run: "hg externals --help"
hg status hook
You can also expand your stat command by adding hook:
[hooks] post-status = python:hgexternals.extstatushook
It will display externals status similar way Subversion does.
Currently extstatushook does not recognize any option specific to hg stat. It should support global options as --repo. It will warn you that option is not recognized and wont produce output. Hovever it does support nodes on which should stat be ran.
From this version EXTERNALS or .hgexternals can be placed ONLY in repository root.
