+## Manual pages

+w64devkit includes manual pages for its commands: GCC, Binutils, GDB,
+Make, CMake, Ccache, ctags, Vim, the BusyBox utilities, and w64devkit's
+own tools. Read them with `man`, e.g. `man gcc` or `man 7 cmake-commands`,
+including for prefixed names like `x86_64-w64-mingw32-ld`. Pages are
+formatted by w64devkit's own `nroff`, which also displays pages that are
+not installed: `man ./page.1`. Set `MANPATH` to add directories of your
+own pages, organized like `share/man`.
