# You need to ensure the following variables are defined. They are traditionally defined
# in distmaker.conf but you can also defined them as an environment variable or by
# calling the script with env DM_REF_CORE=4.7 (for example).
#
# DM_SOURCEDIR=/home/user/svn/civicrm           <- sources
# DM_GENFILESDIR=/home/user/generated           <- generated files
# DM_TMPDIR=/tmp                                <- temporary files (will be deleted afterwards)
# DM_TARGETDIR=/tmp/outdir                      <- target dir for tarballs
# DM_REF_CORE=master                            <- Git branch/tag name
#
# Optional variables
# DM_PHP=/opt/php5/bin/php                      <- php5 binary
# DM_RSYNC=/usr/bin/rsync                       <- rsync binary
# DM_VERSION=trunk.r1234                        <- what the version number should be
# DM_ZIP=/usr/bin/zip                           <- zip binary
