# Will find the rdoc paths of your local gems and generate a html index frameset which will let you select
# the desired gem's rdoc from a dropdown navigation...
#
# Specify your local gems installation's doc directory and the desired html output path, open the generated index.html
# in the output path in your favorite browser and add a boomark.
# You might want to add the script into your path for easy access or put it in a cron job.
# 
# Tested on Ubuntu 8.10, but really should work anywhere with proper gem install path set

# Migration tool from SVN to git
# ==============================

#
# This is not meant for usage in an actual shell script - you're better off running 
# each individual block (marked by the comments) separately and check the output to see if everything
# went right - this is more a writeup of the required steps so I can remember them rather than a 
# shoot-and-forget-solution.

# Migration Tool for Redmine issue and time entry comments from SVN revisions to Git (i.e. r1234 => commit:abcdef789)
# ==============================
# (c) 2009 Christoph Olszowka & Sebastian Georgi, Capita Unternehmensberatung
#
# We used this when we migrated two of our main repositories from svn to git (see http://gist.github.com/139478)
# and wanted to have our revision links in Redmine reflect that change, too.
