# Shows one way to write a self-extracting archive file.
# This is not intended for production use, and it always extracts to a
# subdirectory with a fixed name.
# Plus, it requires Perl and A::Z to be installed first.
#
# In general, you want to provide a stub that is platform-specific.
# You can use 'unzipsfx' that it provided with the Info-Zip unzip program.
# Get this from http://www.info-zip.org .
