cv - convert between metafile formats
cv [ -r ][ file .. ]
Cv reads each human readable metafile file in sequence and converts it
to a binary form. If the option -r is specified, the reverse
conversion is performed.
If no input files are specified, the standard input is read.
To convert the binary file meta.bin to its human-readable equivalent,
and put the result in meta.human
cv -r meta.bin > meta.human
