# This file is a modified version of the gen_embedded script included in the
# scripts directory of seasocks (version 1.1.2). It has been modified to
# recursively find the web files itself, which was originally done by piping
# in the results from a "find" shell command.

# The embedded files includes only those that are required for the server to run
# (including 404 files, a default index page, favicon, etc.)
