Load multiple .hgrc files - ie, some with machine-specific settings?

Question

I\'d like to keep two ~/.hgrc files: ~/.hgrc and ~/.hgrc.local – one with \"standard\" settings (eg, username), the other with machine-specific settings (eg, se

Mercurial checks for a number of configuration files with a specific priority. This way you can have global, user-specific and repository-specific settings. Mercurial version >= 1.4 has a hg help config command which describes this in a nice overview:

$ hg help config
Configuration Files

    Mercurial reads configuration data from several files, if they exist. Below we list the most specific file first.

    On Windows, these configuration files are read:

    - "\.hg\hgrc"
    - "%USERPROFILE%\.hgrc"
    - "%USERPROFILE%\Mercurial.ini"
    - "%HOME%\.hgrc"
    - "%HOME%\Mercurial.ini"
    - "C:\Mercurial\Mercurial.ini"
    - "HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial"
    - "\Mercurial.ini"

    On Unix, these files are read:

    - "/.hg/hgrc"
    - "$HOME/.hgrc"
    - "/etc/mercurial/hgrc"
    - "/etc/mercurial/hgrc.d/*.rc"
    - "/etc/mercurial/hgrc"
    - "/etc/mercurial/hgrc.d/*.rc"

    The configuration files for Mercurial use a simple ini-file format. A configuration file consists of sections, led by a "[section]" header and followed by
    "name = value" entries:

      [ui]
      username = Firstname Lastname 
      verbose = True

    This above entries will be referred to as "ui.username" and "ui.verbose", respectively. Please see the hgrc man page for a full description of the possible
    configuration values:

    - on Unix-like systems: "man hgrc"
    - online: http://www.selenic.com/mercurial/hgrc.5.html

You can list your current settings with hg showconfig.
