-Source location
----------------
-
--   The main source for string functions is located at:
-    ``libc/src/stdio`` with subdirectories for internal implementations.

----------------------
-
-Formatted Input/Output Functions
-================================
-
-These functions take in format strings and arguments of various types and
-convert either to or from those arguments. These functions are the current focus
-(owner: michaelrj).

-``FILE`` Access
-===============
-
-These functions are used to interact with the ``FILE`` object type, which is an
-I/O stream, often used to represent a file on the host's hard drive. Currently
-the ``FILE`` object is only available on linux.

-Operations on system files
-==========================
+Macros
+======
 
-These functions operate on files on the host's system, without using the
-``FILE`` object type. They only take the name of the file being operated on.

-Unformatted ``FILE`` Input/Output Functions
-===========================================
+Functions
+=========
 
-The ``gets`` function was removed in C11 for having no bounds checking and
-therefor being impossible to use safely.
