SvarCOM is the SvarDOS command line interpreter, known usually under the name
6
"COMMAND.COM". It is designed and maintained by Mateusz Viste, and distributed
7
under the terms of the MIT license.

For the time being, it is a work-in-progress project that is not entirely
10
complete yet. SvarCOM version 2021.0 must be considered as a "preview"
11
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:
17
 - no support for pipes (eg. file.exe | more)
474 mateuszvis 18
 - no support for advanced batch constructs (conditionals, errorlevels...)
473 mateuszvis 19
 - 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
474 mateuszvis 22
functionaly equivalent to COMMAND.COM from MS-DOS 5.x/6.x. No LFN support.
