+# This script aims to do averything 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.
+
+# This script is written as a bunch of subroutines. You'll probably
+# only need to build a couple of the packages (dtl, aspell) once.
+# Thereafter, the invocation of these subroutines can be commented out.
+# (See the end of the script.)
+
+# Notes:
+# It uses the MinGW/MinSYS environment and 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, libiconv-2.dll,
+#   mingw10.dll and clean_dvi.py exist.
+# It compiles the dv2dt and dt2dv utilites.
+# It compiles and installs the Aspell library.
+# It compiles and installs LyX.
+# It copies the dv2dt and dt2dv utilites, the .dlls and
+#   clean_dvi.py to the lyx package.
+# It modifies the Resources/lyx/configure script to
+#   ensure that the generated .dvi file is usable.
+
+# 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".
+
+# It compiles the static version of the Aspell libraries because no
+# .dll version exists.
