# This script will automates the steps used to producing a win32 package
# of SoX.
#
# It is used on a Fedora box with mingw32 cross compiler and wine to
# test.
#
# It will optionally package up VC++ version of wget if found in
# ../wget-1.11.4.
#
# Various notes:
#
# The following command lines were used to generate the external libraries
# SoX ships with.
#
# Needed for libltdl support.
# FIXME: Install
# cd libtool-2.4.2
# mingw32-configure --disable-shared --enable-static;mingw32-make;sudo mingw32-make install
