"""Operations on trees with nested Mercurial repositories.

​

This extension provides commands that apply to a composite tree called

a forest. Some commands simply wrap standard Mercurial commands, such

as 'clone' or 'status', and others involve a snapshot file.

​

A snapshot file represents the state of a forest at a given time. It

has the format of a ConfigParser file and lists the trees in a forest,

each tree with the following attributes:

​

  root          path relative to the top-level tree

  revision      the revision the working directory is based on

  paths         a list of (alias, location) pairs

​

The 'fsnap' command generates or updates such a file based on a forest

in the file system. Other commands use this information to populate a

forest or to pull/push changes.

​

​

Configuration

​

This extension recognizes the following item in the forest

configuration section:

​

walkhg = (0|no|false|1|yes|true)

​

  Whether repositories directly under a .hg directory should be

  skipped (0|no|false) or not (1|yes|true). The default value is true.

  Some commands accept the --walkhg command-line option to override

  the behavior selected by this item.

​

partial = (0|no|false|1|yes|true)

​

  Whether fpull should default to partial. The default value is 0.
