libc Documentation
==================

The libc documentation is written using the Sphinx documentation generator. It is
currently tested with Sphinx 1.1.3.

To build the documents into html configure libc with the following cmake options:

  * -DLLVM_ENABLE_SPHINX=ON
  * -DLIBC_INCLUDE_DOCS=ON

After configuring libc with these options the make rule `docs-libc-html`
should be available.
