gno/usr.bin/catrez/catrez.c
gdr c7a0146f19 - use getopts to parse parameters (so that -av works like -a -v) 
- print error messages on stderr instead of stdout
  - change man page to use bold font in a couple of places and add history
  - update other documentation to reflect changes in making catrez
    part of the standard GNO release
  - added test cases in "tests" directory
