# ttx_shellext_win32
# v1.04 matches ttLib 1.0a6

# This script installs a Windows 9x/NT shell extension for TTX
# After installing it, click with the right mouse button on a TrueType file
# and choose "[TTX] Convert current TrueType to XML" from the context menu
# to start the ttDump.py program with the selected TrueType file
# or "[TTX] Convert all TrueType to XML" to start the ttDump.py program 
# with all TrueType files in the current directory. 
# The other way around works analogically.
