# This script takes the following inputs:
#
# * a HTML file
# * a series of flag names
#
# It parses, the HTML file, enables/disables sections of the makrup based
# on conditional comments and flag values, then outputs a new HTML file.
#
# Example:
#
# in.html:
#   <!--{if foo}>
#     FOO!
#   <!{else}-->
#     BAR!
#   <!--{endif}-->
#
# $ ship.py --i in.html --o test-out.html --enable foo
#
# out.html:
#   <!--{if foo}-->
#     FOO!
#   <!--{else}>
#     BAR!
#   <!{endif}-->
#
# Only if-else-endif are currently supported.  All conditional comment expressions must
# be on one line with no other non-whitespace characters.
