== Getting development information and code history from SVN ==

 * "!ChangeLog" style file: install and run [http://ch.tudelft.nl/~arthur/svn2cl/ svn2cl]
 * File history in SVN:

{{{
    cd path/to/directory/
    svn log [file.c]

    # or time reverted:
    svn log [file.c] | tac
}}}

 * Bug: svn2cl !ChangeLog loses file names at branch point. Problem and possible solution described here:

== Switch the repository ==

To switch from SVN 'trunk' (now GRASS 7 development) to 'develbranch_6' (now GRASS 6.4 development) use

{{{
    cd /path/to/your/local/copy/trunk
    svn switch https://svn.osgeo.org/grass/grass/branches/develbranch_6 .
}}}

The switch command preserves local, uncommited changes.

== SVN usage ==

=== Merge between branches (backporting) ===

Run the command from within the target branch.
 * Example 1: pull a change from trunk into the 6.3 release branch:
{{{
    cd releasebranch_6_3/
    svn merge -c 30749 https://svn.osgeo.org/grass/grass/trunk
}}}

where {{{30749}}} is the revision number of the changeset you wish to backport.

 * Example 2: merge a change from the 6.4 development branch into GRASS 7 (trunk):
{{{
    cd trunk/
    svn merge -c 31154 https://svn.osgeo.org/grass/grass/branches/develbranch_6

}}}
