                               === 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:

 - no support for pipes (eg. file.exe | more)

 - no support for advanced batch constructs (conditionals, errorlevels...)

 - a few internal commands missing: CALL, CTTY, GOTO, IF, LH, SHIFT

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.

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 exception of the 'PAUSE' command.
