                               === 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.

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.

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 %DOSDIR% for SvarCOM to be able to output
messages in non-english languages. SvarCOM's language is controlled by the
%LANG% environment variable.

=== INTERNAL COMMANDS ========================================================

SvarCOM implements the following internal commands. For help on each command,
run it with a "/?" argument.

BREAK       - sets or clears extended CTRL+C checking
CALL        - calls a batch file from within another batch file
CD/CHDIR    - displays the name of or changes the current directory
CHCP        - displays or sets the active code page number
CLS         - clears the screen
COPY        - copies one or more files to another location
DATE        - displays or sets the system date
DEL/ERASE   - deletes one or more files
DIR         - displays a list of files and subdirectories in a directory
ECHO        - displays messages, or turns command-echoing on or off
EXIT        - quits the command.com program (command interpreter)
FOR         - runs a specified command for each element in a list
GOTO        - directs batch processing to a labelled line in the batch program
IF          - performs conditional processing in batch programs
LN          - adds, deletes and displays global executable links
MD/MKDIR    - creates a directory
PATH        - displays or sets a search path for executable files
PAUSE       - suspends processing of a batch program
PROMPT      - changes the DOS command prompt
RD/RMDIR    - removes (deletes) a directory
REM         - records comments (remarks) in a batch file
REN/RENAME  - renames one or more files or directories
SET         - displays, sets or removes DOS environment variables
SHIFT       - changes the position of arguments in a batch file
TIME        - displays or sets the system time
TRUENAME    - returns a fully qualified path or filename
TYPE        - displays the contents of a text file
VER         - displays the DOS kernel and SvarCOM shell versions
VERIFY      - tells DOS whether to verify that files are written correctly
VOL         - displays the disk volume label and serial number


=== INSTALLATION =============================================================

Installing SvarCOM requires to either copy it to the root of your boot drive
replacing your current COMMAND.COM, or adding a SHELL directive to your
CONFIG.SYS file to instruct DOS that it should load SvarCOM as its shell, eg.:

  SHELL=C:\SVARCOM\COMMAND.COM /P

Some DOSes support a SHELLHIGH directive that loads the shell in high memory.
It is pointless to use it to load SvarCOM. SvarCOM will load its resident part
as high as possible on its own, enforcing this through SHELLHIGH could even
be harmful since SvarCOM wouldn't be able to relocate to the highest address
as it would be allocated by SHELLHIGH already.

SvarCOM supports multiple languages. To enable SvarCOM using them it is
necessary to define an NLSPATH environment variable that would point to a
directory and copy the SVARCOM.LNG file there. Once done, SvarCOM will try
loading whatever language is being set up in the LANG environment variable.
