; COMPRESS.DWN for DOWNSORT by Rob Hamerling
;
; This is a modified version of the 'standard' COMPRESS.CFG such as delivered
; with Maximus and Squish. See for a complete and annotated version the
; original in the Maximus and/or Squish software packages.
;
; This file is dedicated for use by Downsort for the import of File_Id.Diz.
; 'Dedicated' means that it is optimized for use by Downsort.
; But the original might be used as well, only some parameter specification
; may be not that efficient for use with Downsort, and some may cause
; failure of extracting File_Id.Diz.
;
; Main differences with the original Compress.Cfg:
;
; - Only Extract operations are specified, since this is the only type
; of operation used by Downsort
; - All parameters are optimized for one task: extract File_Id.Diz
; - For each unarchiver the version is indicated for which the parameters
; are appropriate. Other versions may need different parameters.
;
; Some special notes with regard to unarchivers for Downsort:
;
; For performance reasons Downsort calls the unarchiver directly (not via
; the command shell).This means for example that under OS/2 you should
; not specify a DOS unarchive program, and vice versa. It simply does not
; work! The OS/2 version of Downsort checks for callability and if the
; specified unarchiver is not callable (or not found!) it ignores the
; corresponding archive type for extraction of File_ID.Diz.
; The DOS-version of Downsort has no check.
;
; Some reasons why importing of File_ID.Diz by Downsort may not work:
; - The archive does not contain a file File_Id.Diz.
; - The unarchiver is of a lower, incompatible version than the archiver
; with which the archive was built.
; Use always the most recent version of UNarchivers.
; - The file is wrongly recognized as an archive of a different type.
; It may help if you change the specification sequence in Compress.Dwn.
; - Wrong parameter specifications in Compress.Dwn.
; Note: Normally you want NOT to overwrite a newer file. But in this
; case only File_Id.Diz will be extracted to the current directory.
; So it is no problem to overwrite a left over from a previous extract!
; Not always will an appropriate error message appear!
; - The archive program cannot be called by Downsort, see above.
; - Most unlikely (but you never know) a bug in Downsort!
