pemit

This is a utility to pem-encode data. It requires a PEM type to be
specified via the `-t` flag. Any number of files may be specified on
the command line; alternatively, if no arguments are provided or the
only argument is "-", pemit will read from standard input.

Example of standard input:
	$ dd if=/dev/zero bs=32 count=1 | pemit -t "NULL DATA" 
	1+0 records in
	1+0 records out
	32 bytes (32 B) copied, 8.8908e-05 s, 360 kB/s
	-----BEGIN NULL DATA-----
	AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
	-----END NULL DATA-----
	$ dd if=/dev/zero bs=32 count=1 | pemit -t "NULL DATA" -
	1+0 records in
	1+0 records out
	32 bytes (32 B) copied, 3.1041e-05 s, 1.0 MB/s
	-----BEGIN NULL DATA-----
	AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
	-----END NULL DATA-----

Using files:
        $ dd if=/dev/zero of=fileA bs=32 count=1
	1+0 records in
	1+0 records out
	32 bytes (32 B) copied, 9.0908e-05 s, 352 kB/s
        $ dd if=/dev/zero of=fileB bs=32 count=1
	1+0 records in
	1+0 records out
	32 bytes (32 B) copied, 9.0908e-05 s, 352 kB/s
	$ pemit -t NULL\ DATA fileA      
	-----BEGIN NULL DATA-----
	AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
	-----END NULL DATA-----
	$ pemit -t NULL\ DATA fileA fileB
	-----BEGIN NULL DATA-----
	AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
	AAAAAAAAAAAAAAAAAAAAAA==
	-----END NULL DATA-----
