#! /bin/sh

# This script aims to do everything necessary to automate the building
# of a LyX/Win package.

# Invocation:
# sh build_lyxwin.sh "1.3.6-pre23"
# The string will be shown in the "About LyX" dialog.

# Notes:
# It uses the MSYS environment and MinGW compiler.

# It asks whether the Qt and LyX cvs trees are up to date.
# It asks whether the Qt library has been compiled.
# It checks that qt-mt3.dll, mingw10.dll and clean_dvi.py exist.
# It compiles the dv2dt and dt2dv utilites.
# It compiles and installs LyX.

# Once all this is done, you're ready to "package" LyX.
# See the README for details.

# The script compiles the .dll version of the Qt libraries. Linking of LyX
# against this will, therefore, take "some time".

# You may need to change these four variables.
