This is the base code of EControl Syntax Editor SDK (original site was http://econtrol.ru,
since 2024 the site is free to re-register by anybody).
Reworked and ported from Delphi to Lazarus by Alexey Yu. Torgashin (http://uvviewsoft.com),
now it requires ATSynEdit package for Lazarus.

Code contains:
- syntax parser
- grammar parser
- regex engine (parser requires it, it cannot use FPC RegExpr unit)
- lexer manager (linked list of lexers)
Code does not contain:
- SyntaxMemo control
- ecMemoStrings class
- popup listbox classes
- other visual controls

Code is modified, to work with ATSynEdit
(ecMemoStrings class deleted, replaced with ATStringBuffer class [same methods, much less code]).
