XWRT (XML-WRT) это эффективный компрессор HTML/XML файлов (но работает и на остальных текстовых данных). Он преобразует XML в более сжимаемый формат и затем использует zlib, lzma, PPMd или lpaq6 в качестве конечного сжатия.
Usage: XWRT.exe [options] <file1> [file2] [file3] ...
where <file> is a XML file or a XWRT compressed file (it's auto-detected)
you can also use wildcards (e.g., "*.xml")
GENERAL OPTIONS (which also set default additional options):
-l0 = no compression (memory usage up to 16 MB)
-l1 = zlib fast (memory usage 16+1 MB)
-l2 = zlib normal (default, memory usage 16+1 MB)
-l3 = zlib best (memory usage 16+1 MB)
-l4 = LZMA dict size 64 KB (memory usage 16+9 MB for compression and 16+3 MB for decompression)
-l5 = LZMA dict size 1 MB (memory usage 16+18 MB for compression and 16+3 MB for decompression)
-l6 = LZMA dict size 8 MB (memory usage 16+84 MB for compression and 16+10 MB for decompression)
-l7 = PPMd model size 16 MB (memory usage 16+20 MB)
-l8 = PPMd model size 32 MB (memory usage 16+36 MB)
-l9 = PPMd model size 64 MB (memory usage 16+70 MB)
-l10 = lpaq6 model size 120 MB (memory usage 16+104 MB)
-l11 = lpaq6 model size 214 MB (memory usage 16+198 MB)
-l12 = lpaq6 model size 406 MB (memory usage 16+390 MB)
-l13 = lpaq6 model size 790 MB (memory usage 16+774 MB)
-l14 = lpaq6 model size 1560 MB (memory usage 16+1542 MB)
-0 = preprocessed and uncompressed output optimized for further LZ77 compression
-1 = preprocessed and uncompressed output optimized for further LZMA compression
-2 = preprocessed and uncompressed output optimized for further PPM compression
-3 = preprocessed and uncompressed output optimized for further PAQ compression
ADDITIONAL OPTIONS:
-bX = Set maximum buffer size while creating dynamic dictionary to X MB
-c = Turn off containers (without number and word containers)
+d = Turn on usage of the static dictionary (requires wrt-eng.dic,
which is available at http://pskibinski.pl/research)
-eX = Set maximum dictionary size to X words
-fX = Set minimal word frequency to X
-i = Delete input files
-mX = Set maximum memory buffer size to X MB (default=8)
-n = Turn off number containers
-o = Force overwrite of output files
-pX = Preprocess only (file_size/X) bytes in a first pass
-s = Turn off spaces modeling option
-t = Turn off "try shorter word" option
-w = Turn off word containers
