Bring in the 4.4 Lite games directory, modulo man page changes and segregation of the x11 based games. I'm not going to tag the originals with bsd_44_lite and do this in two stages since it's just not worth it for this collection, and I've got directory renames to deal with that way. Bleah.

.SH SYNOPSIS
.B factor
added -h flag to allow for hexidecimal output. Use '0' for base rather than 10 to allow for more flexible input bases. Inspired by changes in PR 7402, but mostly redone by me to get past bde filter. Submitted by: Timo J. Rinne PR: 7402

The

Fix printf errors in the hflag case. Fix old bug with bogus casing to (long). Document the true limits of factor on 64-bit architectures. Submitted by: bde

utility will factor integers between 0 and ULONG_MAX (4294967295 on 32
bit architectures, 18446744073709551615 on 64 bit ones), inclusive.

When a number is factored, it is printed, followed by a ``:'',
and the list of factors on a single line.
Factors are listed in ascending order, and are preceded by a space.
If a factor divides a value more than once, it will be printed
more than once.

.PP
When
.I factor
is invoked with one or more arguments,
each argument will be factored.
.PP
When
.I factor
is invoked with no arguments,
.I factor
reads numbers, one per line, from standard input, until end of file or error.
Leading white-space and empty lines are ignored.
Numbers may be preceded by a single - or +.
Numbers are terminated by a non-digit character (such as a newline).
After a number is read, it is factored.
Input lines must not be longer than 255 characters.
.PP
The
.I primes
utility prints primes in ascending order, one per line, starting at or above
.B start
and continuing until, but not including
.B stop.
The
.B start
value must be at least 0 and not greater than
.B stop.\&
The
.B stop
value must not be greater than 4294967295.
The default value of
.B stop
is 4294967295.
.PP
When the
.I primes
utility is invoked with no arguments,
.B start
is read from standard input.
.B Stop
is taken to be 4294967295.
The
.B start
value may be preceded by a single +.
The
.B start
value is terminated by a non-digit character (such as a newline).
The input line must not be longer than 255 characters.

.SH DIAGNOSTICS
Out of range or invalid input results in `ouch' being
written to standard error.
.SH BUGS
.I Factor
cannot handle the ``10 most wanted'' factor list,
.I primes
won't get you a world record.
