zlib-ng/CMakeLists.txt
Hans Kristian Rosbach aeffa9bbf4 Remove misleading manpage. 
README.md changes:
- Added a related projects section at the end.
- Added blank line after header where missing.
- Added extra blank line before header to make them easier to spot as plain-text.
- Changed line-length for Contributing section, to make it more readable as plain-text.
