 * This language specification file supports for syntax checking on
 * a large subset of Perl 5.x.
 * The basic common syntax of Perl is fully supported, but as for
 * the highlighting of built-in operations, it's mainly designed
 * to support for hightlighting Perl code in a Safe environment (compartment)
 * as used by CoMaNet for evaluation of administrative scripts. This Safe
 * compartment basically allows for all of Opcode's :default operations,
 * but little others. See http://perldoc.perl.org/Opcode.html to learn
 * more.
