PPK 1.1, part of the UnSquish distribution ========================================== PPK is a simple Powerpacker compressor. I wrote it for myself, but decided to include in in this distribution as others might benefit from it. It requires powerpacker.library v36 or above, included in the libs/ directory. PPK requires AmigaOS release 2.00 or greater (Exec v36 or above). Usage ¯¯¯¯¯ Shell usage only. There's no icon, and it won't run from Workbench. Format: PPK [EFFICIENCY ] [SPEEDUP ] [SUFFIX] [MEMHOG] Template: PPK FILE/A,EFF=EFFICIENCY/K,SP=SPEEDUP/K,SUFF=SUFFIX/S,MEMHOG/S The simplest usage of PPK is to type PPK foo to compress the file "foo". PPK will default to "best" efficiency, and a large speedup buffer. The compressed file will replace the decompressed file. PPK may be aborted by pressing Ctrl-C. The EFFICIENCY parameter can be used to override the default efficiency. You may specifiy FAST, MEDIOCRE, GOOD, VERYGOOD or BEST. Alternatively, you may supply a numeric argument between 1 and 5; 1 corresponding to FAST and 5 to BEST. For example, to crunch file "foo" with "mediocre" quality: PPK foo efficiency=mediocre or PPK foo efficiency=2 EFFICIENCY may be abbreviated to EFF, ie PPK foo eff=2 The SPEEDUP parameter (which may be abbreviated to SP) sets the size of the speedup buffer. You may choose between SMALL, MEDIUM and LARGE. Again, a numeric argument (1, 2, or 3) may be specified. Eg to crunch file "bar" with a small speedup buffer, do PPK bar speedup=1 or PPK bar speedup=small or PPK bar sp=1 etc The SUFFIX switch (which may be abbreviated to SUFF) causes PPK to append a .pp suffix to the file after it has been crunched, and not to delete the original file. This is similar to XPK's -s switch. Some files get bigger before they get smaller. PPK will abort with a buffer overflow if this happens. If you get a buffer overflow, you might try setting PPK's MEMHOG switch. This causes PPK to allocate twice as much memory as it needs, in order to provide a big enough buffer to prevent buffer overflow. Sometimes it works. PPK is pure and may be made resident.
