MERCURIAL_INSTALL_PROMPT = '''
Mercurial releases a new version every 3 months and your distro's package
may become out of date. This may cause incompatibility with some
Mercurial extensions that rely on new Mercurial features. As a result,
you may not have an optimal version control experience.

To have the best Mercurial experience possible, we recommend installing
Mercurial via the "pip" Python packaging utility. This will likely result
in files being placed in /usr/local/bin and /usr/local/lib.

How would you like to continue?

1) Install a modern Mercurial via pip (recommended)
2) Install a legacy Mercurial via apt
3) Do not install Mercurial
