# Description:
#
# Script for copying directory contents or SVN project
# to Telelogic Synergy (CCM) project.
#
# The target directory specified in <ccm_path> parameter must
# exist in ccm version control before this script is executed.
#
# If SVN URL and revision are specified the <svn_path>
# directory must not exist.
#
# Script performs the following steps:
# 1) If SVN URL and revision are specified, exports SVN project
#    to <svn_path> directory.
# 2) Creates S60 distribution policies to <svn_path> directory
#    using setpolicyfiles.py script.
# 3) Makes CCM sync and reconf for the CCM project.
# 4) Creates CCM default task.
# 5) Synchronizes the <svn_path> and <ccm_path> directories.
# 6) If there were any changes, reconciles CCM project to database
#    and commits CCM default task. If there were no changes, leaves
#    the CCM default task open.
#
# The script execution aborts immediately if any error occurs.
# In this case the user must manually delete the ccm task and
# reconcile the ccm work area so that it is again
# in the same level as it was before script execution.
#
# Usage:
# python -u svn2ccm.py [-c "<comment_string>"] [-u <url>] [-r <revision>] <svn_path> <ccm_path> <ccm_project_id> <ccm_project_release>
# For example:
# python -u svn2ccm.py -c "Update from SVN release 7010" -u http://host/path -r 7010 X:\java C:\ccm_wa\java jrt-java s60_release > svn2ccm.log 2>&1
