The name ArcMaster is short for the term Archive Master where the word
  archive means a place where documents and/or records are kept.  In the
  modern world of personal computing, these documents and records are
  maintained in computer files.  These files are frequently compressed and
  grouped together in archive files by special computer programs such as
  PKZIP, ARCA, PAK, LHA, and ARJ.  All of these special programs are operated
  from the DOS command line and require the entry of numerous and varied
  command line switches in order to maximize their utility.

       ArcMaster, hereafter known as AM for short, is an archive program
  interface control system.  It provides a clean interface that removes the
  burden of remembering all the various command line switches and options that
  may be used with archiving programs.  In addition, AM is a powerful and
  flexible DOS shell that provides numerous ways in which the user can
  maintain and manipulate his/her DOS directory and file structures.

       AM may be used as a stand-alone program in its useful role as a DOS
  shell, but in order to manipulate compressed archive files the user must
  have present in his/her system at least one of the supported archive
  programs.  A list of supported compression/decompression archive programs
  appears in the next chapter.
