| Hi!
Precomp is a command-line file precompressor. It decompresses deflate/
zLib/LZW streams in files (for example PDF, SWF, ZIP, GIF, JAR, PNG)
and ensures they can be recompressed bit-to-bit-identical.
The output file is larger, but can usually be compressed better than
the original file with good compressors like UHArc or PAQ. PDF files,
for example, usually shrink to 25-50% of their original size.
lprepaq v1.0 is a combination of Precomp v0.3.5 and lpaq1 by Matt
Mahoney (http://cs.fit.edu/~mmahoney/compression/#lpaq1). It is a
complete file compressor/decompressor, so there is only one step
needed to (de)compress files.
Version 0.3.5 of Precomp fixes a bug in the GIF implementation that
led to crashes (thanks to Stephan Busch).
Please report any bugs for lprepaq, because it is the first released
version.
