00TODO: Tasks left to accomplish before rc is complete

Consider
  Make return code and error definitions unique to OSSP rc.
  Enclose rc.c in its own project and write autoconf logic.

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

Automated environment
  Solve problem discussed at OpenPKG eval meeting.
