00TODO: Tasks left to accomplish before rc is complete

Consider
  Make return code and error definitions unique to OSSP rc.
  Offer include directive in config file.
  Standardize rc.conf.
    Rename rc.conf to rc.config.
    New rc.conf specifies options like syslog.conf or resolv.conf does.

Must do
  Translate rc bourne shell script to ANSI C.
  Finish man page. Start latex or Docbook guide.
  If a variable is defined for which no default exists, warn user (Scholli.)
  Avoid a silent failure when giving non-existent run commands (Marcus.)

Possible problems
  Abstract syntax of rc.file identifiers
    Need to recognize language syntax, i.e. set, block von XML?
    Is a regex enough to describe a syntax or do we need more?
    Cases XML, M4, asn.1, ...

Automated environment
  Stock rc.func includes AddPath, DelPath, PermMask.
  Reccommended .bashrc includes rcEnter() and rcExit().

Error handling
  Classic error, give 'restart' command in place of 'start' to stopped prog
