                               === SVARCOM ===


SvarCOM is the SvarDOS command line interpreter, known usually under the name
"COMMAND.COM". It is designed and maintained by Mateusz Viste, and distributed
under the terms of the MIT license.

For the time being, it is a work-in-progress project that is not entirely
complete yet. SvarCOM version 2021.0 must be considered as a "preview"
version.

The goal is to make SvarCOM the default SvarDOS shell, replacing FreeCOM.
Why replacing FreeCOM, you ask? See FREECOM.TXT for details.

Since SvarCOM is a work-in-progress effort, it is missing a few things yet:
 - pipes (cmd.exe | more) and stdin redirections (cmd.exe < file)
 - advanced batch constructs (conditionals, errorlevels...)
 - a few internal commands missing: CALL, CTTY, GOTO, IF, LH, SHIFT
 - DIR misses a few switches (/S, /O, /A)
 - ... (see TODO.TXT for more information)

SvarCOM is minimalist and I'd like to keep it that way. It aims to be
functionaly equivalent to COMMAND.COM from MS-DOS 5.x/6.x. No LFN support.

As of version 2021.0, SvarCOM's resident footprint is under 2 KiB.

Translation strings are stored in the file SVARCOM.LNG, which should be
placed in a directory pointed at by %NLSPATH% for SvarCOM to be able to output
messages in non-english languages. SvarCOM's language is controlled by the
%LANG% environment variable. NOTE: at this time translations aren't available
yet, with the proof-of-concept exceptions of the 'PAUSE' and 'SHIFT' commands.
