Run sh install.sh

This will just copy the sgn executable to your /usr/local/bin directory.

cd into a subversion working copy and gently rub the lamp running sgn:
the genie will grant you three wishes.

This utility covers a single usage pattern, but aims to do it well.

The pattern is:

• You have a svn repo with a trunk and one or more branches
• All new work is committed first to the trunk
• It is regularly merged to the branches (example: production branch)

This utility hopefully makes this much less frustrating allowing you to:

• Commit to trunk
• Check that all is good and/or wait for production clearance
• svn switch to the production branch
• sgn (gently rub the lamp)
• You will be presented with a list of unmerged commits, you can now choose to
  merge all of them or just some.
• All will be duly recorded in the standard svn mergeinfo property

This has been tested with subversion 1.6 and 1.7.
This should theoretically work with 1.5 as well.
