# This file is included by the other shell scripts to set up some variables.
# Each of the scripts (including this) gets 2 arguments: <config> <branch>

# It sets the following variables:
# - CONFIG   : configuration (default, debug, syncdebug, etc.)
# - BRANCH   : branch (master, etc.)
# - CONFIG_  : $CONFIG wrapped in [] or empty if CONFIG=default
# - BRANCH_  : $BRANCH wrapped in {} or empty if BRANCH=master
# - REV      : output of `git describe --tags'
# - SOURCEDIR: absolute path to the source directory
# - BUILDDIR : absolute path to the build directory
# - TMP_BASE : folder for temporary work items
# - TMP_PATH : $TMP_BASE/$CONFIG/$BRANCH/$REV
# - VERSION_ : version string, unsafe, may include special characters
# - VERSION  : sanitized version string, suitable for filenames

# Quit on error.
