/* tidylib.c -- internal library definitions
(c) 1998-2008 (W3C) MIT, ERCIM, Keio University
See tidy.h for the copyright notice.
Defines HTML Tidy API implemented by tidy library.
Very rough initial cut for discussion purposes.
Public interface is const-correct and doesn't explicitly depend
on any globals. Thus, thread-safety may be introduced w/out
changing the interface.
Looking ahead to a C++ wrapper, C functions always pass
this-equivalent as 1st arg.
