.SH "DESCRIPTION"
.PP
Commas group hex digits into chunks.  Each chunk defines exactly 32
bits of the resultant bitmask.  No chunk may specify a value larger
than 32 bits (-EOVERFLOW), and if a chunk specifies a smaller value
then leading 0-bits are prepended.  -EINVAL is returned for illegal
characters and for grouping errors such as ``1,,5'', ``,44'', ``,'' and "".
Leading and trailing whitespace accepted, but not embedded whitespace.
