Neko runs over the windows

• C standard library (e.g. glibc)
• X11 client-side library (libX11)
• X11 miscellaneous extensions library (libXext)

Build system is not used because there is only one source file that includes all headers. The command below produces oneko executable on the majority of distributions.

clang -Wno-parentheses -std=c11 -pedantic -D_DEFAULT_SOURCE oneko.c -o oneko -lc -lm -lX11 -lXext

The same arguments will work with GCC compiler.

Read the docs.

Patch levels are used for versions compatible with the original oneko. The project will switch to SemVer for versioning after the first feature-breaking change.
