ListCmp - © 1996 By Pasi Ristioja

 With this little utility you can compare filelists, handy if you keep track
 of downloadings and want to check them against some filelist. If you try
 to compare binary files results are unpredictable.

 Some statistic how buffer size affects speed:

 01:30 - new         (buffer 262144)
 01:30 - new         (buffer 131072)
 01:37 - new         (buffer  65536)
 01:43 - new         (buffer  32768)
 01:50 - new         (buffer  16384)
 02:09 - new default (buffer   8192)
 02:58 - new         (buffer   4096)
 03:52 - new         (buffer   2048)
 06:04 - new         (buffer   1024)
 07:29 - new         (buffer    512)
 05:33 - old default (buffer  16384) as you see old was much slower :)

 Test was done using comparing six small (20kb-500kb) list against one large
 bbslist (1.2Mb), both I and E result files were written to same device and
 STRIP & EQU options were used. Results and practise shows that main factor
 is your hd speed.

 Requires: OS3.0, 68020 and asyncio.library

 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 FILE/A

 Cmp filelist.

 FILE/A

 Filelist to compare against.

 These are optional:

 I=INCLUDE/K

 Write matched lines to this file.

 E=EXCLUDE/K

 Write unmatched lines to this file.

 B=BUFSIZE/N/K

 Internal buffersize used for various purposes, default is 8192 and range
 is 256-2^32. If longer line than buffersize is encountered listcmp will
 abort with errorcode 20.

 STRIP=STRIPSUFFIX/S

 Suffix is not compared. Normally line is considired equal if space or
 $a (linefeed) in encountered, this adds dot (.) for this group.

 CASE/S

 Case sensitive compare.

 EQU/S

 Chars _ and - are considered equivalent.

 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Normally you should use command like this:

 ListCmp files.cmp files.bbs I RAM:Include E RAM:Exclude STRIP EQU

 files.cmp     - files what you have
 files.bbs     - files what bbs has
 I RAM:Include - files which were found in both list files
 E RAM:Exclude - files which were only in files.bbs (download these;-) 
 STRIP         - Claudia.gif and Claudia.jpg are equal
 EQU           - Crawford_Nude.gif and Crawford-Nude.gif are equal

 Filelists must be formatted like this:

 <possible spaces> filename <space> description
 <possible spaces> filename <space> description
 <possible spaces> filename <space> description

 If you use STRIP option then it has no meaning what is after dot mark, 
 otherwise there must be space or $a (linefeed) after filename. Note that
 possible spaces before filename are skipped! In practise just use STRIP/EQU
 options and all normal filelists will work ok.
