    NAME
           cdm - CP/M disk manager

    SYNOPSIS
           cdm file...

    DESCRIPTION
           cdm  gives access to the CP/M disk images used by yaze(1).
           With cdm you can create disks, copy files to and from  the
           Unix file system, list files and erase files from the CP/M
           disk.

    OPTIONS
           Any files listed on the cdm command line are taken  to  be
           existing CP/M disk files and they are mounted successively
           to drive A, B, C, ... etc.

           The format of CP/M disk files (<CPM_Disk>) is described in
           yaze.doc and yaze-ag.doc.

    INTERACTIVE COMMANDS
           The  interactive	 interface to cdm mimics an extended CP/M
           clone.  The current disk and user  number  appear  in  the
           prompt  and  can	 be changed by entering DU: as a command,
           where D is any mounted disk letter (a .. p)  and	 U  is	a
           user  number  (cdm  allows  0  ..  31, although you should
           restrict yourself to numbers under 16 to remain compatible
           with CP/M).

           DU: can also be prefixed to any filename, to indicate that
           it is not on the current disk/user.  Two pseudo disks  can
           be  referenced  in the copy command: u and t.  These refer
           to files in the Unix file-system.  `u:file'  refers  to	a
           binary  Unix file and `t:file' refers to a text Unix file.
           The difference  is  that	 u:  files  are	 copied	 verbatim
           whereas	t: files undergo CRLF and ^Z processing appropri−
           ate for the copy direction (to or from CP/M).

           Command names can be shortened to a  unique  abbreviation.
           If  cdm was compiled with GNU Readline, command-line edit−
           ing, filename completion and history recall are	available
           - see the readline documentation.
