Overview
This extension is a convenience wrapper. In the simplest case, hg fetch acts like hg pull -u -- it pulls changes from a remote repository into a local one and updates the working directory. (This is like the "update" command as found in Subversion or CVS.)
If the pulled changes require merging, the fetch extension attempts an hg merge followed by an hg commit.
Configuration
To enable the extension, add the following lines to your .hgrc:
[extensions] hgext.fetch=
Usage
hg fetch [SOURCE]
Where SOURCE is a path or URL.
Use hg help fetch for additional options.
