module Strategy
# Implements the deployment strategy that keeps a cached checkout of
# the source code on each remote server. Each deploy simply updates the
# cached checkout, and then filters a copy through tar to remove unwanted .svn directories,
# finally leaving a pristeen, export-like copy at the destination.
class FilteredRemoteCache < Remote
# Executes the SCM command for this strategy and writes the REVISION
# mark file to each host.
