# Retrieves version information from Capistrano's files. The general approach is










4



# to read the version information (branch name, git SHA, and date deployed) out










5



# of Capistrano's revisions.log file.










6



#










7



# The code is a bit more complicated than it should because Capistrano does not










8



# always update the revision.log file before the application reads this information.










9



# Therefore there is logic in this class to detect if the version information is










10



# stale and re-read it until it is up to date. Because re-reading this file is










11



# an expensive operation we cache the information as soon as we are sure it's










12



# current.
