source: s10k/CommonLibs/quazip-0.7.2/doc/html/classQuaAdler32.html @ 1096

Last change on this file since 1096 was 1096, checked in by s10k, 17 months ago

Added zlib, quazip, basicxmlsyntaxhighlighter, conditionalsemaphore and linenumberdisplay libraries. zlib and quazip are pre-compiled, but you can compile them yourself, just delete the dll files (or equivalent binary files to your OS)
