-// Project: ItsyBitsy window support module
-// Module: itsybits.c
-//
-//
-// ItsyBitsy is a support module that allows you to create windows
-// that look and act very much like a popup window witha system
-// menu and caption bar, except everything is scaled to about 2/3
-// scale.
-//
-// For documentation on how to use ItsyBits, read the document
-// ITSYBITS.DOC.
-//
-// Revisions:
-// 9/27/91 Charlie Kindel (cek/ckindel)
-// Wrote and documented it.
-//
-// 1/14/93 cek
-// 2/23/93 cek Added minimize/maximize buttons.
-// 3/18/93 cek Fixed system menu bug where system menu
-// popped back up if you clicked on the
-// icon again while it was up.
-// 3/24/93 cek More comments. Fixed DS_MODALDIALOG style
-// problem. Use auto precompiled headers
-// in MSVC.
