SIDId V1.09 - Quick & dirty HVSC playroutine identity scanner
Written by Cadaver (loorni@gmail.com), playroutine signatures provided by Ian
Coog, Ice00, Ninja, Yodelking, Wilfred/HVSC & Prof. Chaos. Playroutine info 
file from HVSC crew.

Usage: sidid [directory to scan] [options]

Options:
-a             Scan all files, not just those with .sid extension
-c<configfile> Configfile to use (env.variable SIDIDCFG can also be used)
-d             Do not recurse subdirs
-m             Scan each file for multiple signatures
-o             List only unidentified files
-s<playername> Scan only for specific player
-u             List also unidentified files
-? or --help   Display usage information

Redirect output to file as necessary.

For win32 systems only, the signature configuration file (sidid.cfg) is assumed
to be in the same dir as the executable. Otherwise, it has to be specified
either with the command line option or with the enviroment variable SIDIDCFG.

In the configfile, player signature names must not contain spaces and should be
under 24 letters for neat display. A signature consists of hexadecimal values
and ?? to accept any byte at that position. AND means to skip any number of 
bytes and then continue when the next byte is matched. END ends the current 
signature. Multiple signatures can exist for one player, see for example 
JCH_NewPlayer.

Good signatures should not contain any addresses, not even lowbytes and
preferably also not zeropage, unless it is known that the playroutine is never
zeropage-relocated.

No responsibility whatsoever is taken for the correctness of the existing
signatures! Additional sigs by Yodelking, Ian Coog, ice00 & Wilfred/HVSC.
TED player signatures (tedid.cfg) from Ninja.

Note: DigiOrganizer is listed last in the configfile, so it is not found by
default when a tune contains another recognized playroutine. Use -m to find
out all tunes which use it.
