Latest version 1.2

Version 1.0 

Main difference with previous versions is use of parentheses, quotes
and some extra operators, better macro support (macro, while tstenv
etc.) and signal support. Downward compatibility is not garanteed for
macro's that contain blank lines.

Version 1.1

Fixed a lot of bugs. Changed some test stuff for the sake of
consistency, memtest is NOT downward compatible regarding the exotics.
Not downward comapatible because of following changes:
- domalloc -> malloc
- domemmap -> memmap
- fatal is not there anymore use mabort instead
Added:
- mabort aborts all macro's

Version 1.2

Fixed minor bugs. Added:
commands:
- shift, to shift arguments within macro's
- unset, to remove vars.
- timer, for system time
- syntax check with $CHECK
features:
- chipmunk arguments supports full command lines (incl arguments)
- set supports assignment operators
- VERBOSE refinement
- wildcard char * in several commands (like help env tstenv shomac)
- TRACE prints line numbers;
- added evaluated line TRACE
- filename completion on load, save and syst
- macdef uses readline too
- macro files may have any name (of course .mac is still supported)
- mabort 0  for normal macro exit(no blabla)
- included perror stuff
- consistent error report
bugfix:
- macro's abort on error
- argcount checking
- return values of some commands make sense (like putc and echo return
  number of chars printed)
- comment indent allowed
- cope with sun's bogus errno.h
