  2Core API Documentation
  3======================

  5This is the beginning of a manual for core kernel APIs.  The conversion
  6(and writing!) of documents for this manual is much appreciated!

  8Core utilities
  9==============
 10
 11This section has general and "core core" documentation.  The first is a
 12massive grab-bag of kerneldoc info left over from the docbook days; it
 13should really be broken up someday when somebody finds the energy to do
 14it.
