;MIC command file to build TOPS20 TOOLS master tapes - tape#6
;The only parameter is the name of the tape drive to use:
; $DO T20TAPE6 MT3:
;NOTE that this is a two step process: the first step creates a dummy
;tape listing file (T20TAPEx.TAP), and then writes out the two savesets
;(documentation about the tape is #1, the tools are #2). The tape is
;then rewound, and a directory of the tape is created on top of the
;dummy file. The process is repeated, but this time the real directory
;is written. Those with good eyes will notice the difference in
;file size and creation dates.
