source: s10k/CommonLibs/zlib-1.2.8/contrib/dotzlib/DotZLib/UnitTests.cs@ 1154

Last change on this file since 1154 was 1096, checked in by s10k, 7 years 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)
