NAME
       cv - convert binary data	files between representation formats

SYNOPSIS
       cv in_pat out_pat [[infile] outfile]

DESCRIPTION
       Convert a binary	data file from one representation (format) to another.
       The particular representation desired is	expressed as a set of choices
       from the	pattern: [h|n][s|u] c|s|i|l|d|8|16|32|64. For example, "hui"
       is host unsigned	int, "nl" is network (signed) long. The	default	is
       NETWORK format.

       Host specific format is the native internal number representation used
       inside the computer that	cv is running on. There	is great variation
       between vendors in the host-specific formats that they use. Especially
       for double-precision floating point, DEC, Cray, and IBM have peculiar
       formats and byte	orderings. The network-independent byte	orderings used
       within BRL-CAD is big-endian (most significant bit first, on the	left
       side of the word), twos complement. The network-independent
       double-precision	floating point format used within BRL-CAD is 64-bit
       IEEE 754, transmitted in	big-endian order.

       Signed or unsigned integer formats can be selected. This	has no effect
       on the double-precision format.

       "char", "short",	"int", "long", and "double" provide their C language
       equivalent on this processor when used in "h" host-specific mode. "8",
       "16", "32", and "64" allow more precise specification of	datum sizes
       for "n" network-independent mode.

       For example, to change a	file of	host-specific (machine-specific)
       signed shorts to	a file of network-independent 32-bit integers, the
       input format would be "hss", and	the output format would	be "n32".
