* volmcopy.c

*
|
|
* This program scans a metatape file and prints file count and sizes.
|
|
* It is only for volmgr save images. Save images have the following format:
|
|
* One or more 6144 byte records containing a list of files saved 16 char file
|
|
* name followed my 16 char directory name followed by 16 char volume name.
|
|
* A 1536 byte file definition entry will be followed by 1 to 8 768 byte
|
|
* file data records followed by an EOF for each file. If the file size is
|
|
* greater than 6144 bytes, 1 or more 6144 byte records are output followed
|
|
* by last record modulo 768 bytes. Two EOFs in a row define the EOT.
|
|
* input - stdin or specified filename
|
|
* output - stdout
