  12 # Debian package pre-installation script steps:
  13 #  1) Create log dir/file
  14 #  2) Ensure git-OpenEMR web directory was not previously installed.
  15 #  3) Create config dir/file
  16 #
  17 # Upgrading is not an option here, since this is for testing/evaluation
  18 # of the most current unstable development version of OpenEMR.
