#
# Usage:
#   Optionally set COMPOSER_CMD to allow running composer.
#   Optionally point COMPOSER_VENDOR_DIR to your vendor path for composer.
#
#   Run phan by calling this script:
#     ./run-phan.sh      # Only checks
#     ./run-phan.sh 1    # Regenerate the baseline.txt file
#
#   You can run this from the root directory of dolibarr
#     dev/tools/run-phan.sh
#
#   You can provide the environment variables on the CLI like this:
#     COMPOSER_CMD="php ~/composer.phar" COMPOSER_VENDOR_DIR="~/vendor" ./run-phan.sh
#
#   or export them:
#     export COMPOSER_CMD="~/composer.phar"
#     export COMPOSER_VENDOR_DIR="~/vendor"
#     ./run-phan.sh
#
#  Or some other method
#
