USAGE: ihex -<option> {-|<source>} [-|<destination>]
OPTION:
 -h convert binary file to ASCII-file. Add 2 blank lines at end.
 -d convert binary file to ASCII-file, as -h, but use 2 digit hex only.
 -D convert binary file to ASCII-file, one 2 digit hex per line.
 -r reconstruct ASCII-file to binary file. Stops at 2 blank lines.
 -N convert binary file to ASCII-file, one integer (0..255) per line.
 -A convert binary file to ASCII-file, (0..255) [<char>] per line.
 -n replace <CR><LF> (0x0d 0x0a) by <LF> (0x0a). I.e. DOS to UNIX.
 -m replace <LF><LF> (0x0a 0x0a) by <LF> (0x0a). I.e. single lines.
 -0 replace <CR><LF> (0x0d 0x0a) by <NIL> (0x00). I.e. DOS to C.
 -c replace <LF> (0x0a) by <CR><LF> (0x0d 0x0a). I.e. UNIX to DOS.
 -u replace <CR> (0x0d) by <LF> (0x0a). I.e. OS9 or MAC to UNIX.
 -o replace <LF> (0x0a) by <CR> (0x0d). I.e. UNIX to OS9 or MAC.
 -a replace selected extended ASCII IBM PC codes
    by KEYSYM equivalent and otherwise to inverted question mark.
 -i reverse of -a.
FILES:
   <destination> is always rewritten.
   All diagnostics is written to stderr.
   "-" as <source> is stdin. "-" as <destination> is stdout.
   If <destination> is omitted, output is written to stdout.

USAGE: ihex <file> [<file> ..]
       writes counts of CR (0x0d) and LF (0x0a) to stdout.
USAGE: ihex ?
    writes a table used in -a and -p to stdout.
