// C documentation generator using markdeep.
// - rlyeh, public domain
//
// build:
// cl docs.c && docs ..\..\v4k.h -x=3rd_glad.h,v4k.h,v4k_main.h,v4k_compat.h, > docs.html
//
// how to document:
// - start documentation on a blank line with a /// 3 slashes comment.
// - all comments must be typed right before the symbol declaration.
// - use `see: symbol1,symbol2^` to create links. `^` char indicates an external link.
// - use `keyword: comment` to create tables. `return:` and `returns` are reserved keywords for function returns.
// - use `> code` to create a snippet. snippets will be multi-lined.
// - use `!!! text` to create a note. severity based on number of exclamations (1:note,2:tip,3:warn,4:alert)
//
// exceptions:
// - a ///- comment can be used to exclude a symbol from any further documentation processing.
// - this ///- comment must be appended to any declaration, at the very end of string.
//
// #define my_macro() macro_implementation_here() ///-

// /// return: NULL if not found, found symbol otherwise.
