Directories:

  scripts: Contains helper scripts to do text file to xml type
  specification.

  xml: XML specification of directories and each data type. The
  directory specification is in ./xml/directory.xml. The type
  specifications are in the directory tree below ./xml/ . It mirrors
  the directory structure of under SVN:calib.

Creating types in the database:

  cd ./scripts
  ./make_tables.sh > commands.tmp
  source commands.tmp

  Notes: ./scripts/make_tables.sh writes shell commands to standard
  output. These commands, when executed, create directories and insert
  types into the database by reading the files in the ./xml
  directory. It is assumed that:

    a. ccdbcmd is in the path
    b. make_tables.sh is invoked from the ./scripts directory.
