/* tidylib.c -- internal library definitions

$Revision: 1.75 $
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.
