# Project file (*.hhp) template.  'outname' is the file basename (like
# the pythlp in pythlp.hhp); 'version' is the doc version number (like
# the 2.2 in Python 2.2).
# The magical numbers in the long line under [WINDOWS] set most of the
# user-visible features (visible buttons, tabs, etc).
# About 0x10384e:  This defines the buttons in the help viewer.  The
# following defns are taken from htmlhelp.h.  Not all possibilities
# actually work, and not all those that work are available from the Help
# Workshop GUI.  In particular, the Zoom/Font button works and is not
# available from the GUI.  The ones we're using are marked with 'x':
