Added an environment parser. Cleaned up some memory leaks. Made lc_process() cleanup, so calling lc_process() twice will do nothing. check-in: d7ae2bcb59 user: rkeene tags: trunk

Added a variable type "BOOL_BY_EXISTANCE" that enables things just by being specified. check-in: 307def9899 user: rkeene tags: trunk
21:11
Fixed command line processing and added argument re-ordering. Also, added a global variable lc_optind to indicate where we were in the argv array. check-in: 9d733cc5a2 user: rkeene tags: trunk
