# marc(1)

archive merger

## NAME

marc - archive merger

## SYNOPSIS

**marc** *tgtarc* *srcarc* \[ *files* ... \]

## DESCRIPTION

Reads *files* from the arc archive *srcarc* and add them to the arc archive *tgtarc*.

## HISTORY

*Arc* has been in use in the CP/M and MSDOS world for many years. Thom Henderson developed the original version, but it is important to note that *arc* is based on the file compression theories developed by Huffman, Welch, Knott, Knuth, and many other scientists. This implementation is based on version 5.21 of the MSDOS program.

## BUGS

*Arc* behaves just like the PC version of the program; all functions of the "usage" display are working. Full compatibility with PC ARC files is maintained, the price for which is that *arc* doesn't like long filenames, and can only archive files with names of up to 12 characters. It will \*sometimes\* do The Right Thing with them, but I suggest you put long-winded filenames in a "shar" before *arc*ing them.

There shouldn't be any problems, (hah!) but if you find any, please send them to me at:
