# Construct a link to +url_fragment+, which should be given relative to
# the base of this Sinatra app. The mode should be either
# <code>:path_only</code>, which will generate an absolute path within
# the current domain (the default), or <code>:full</code>, which will
# include the site name and port number. (The latter is typically
# necessary for links in RSS feeds.) Example usage:
#
# url_for "/" # Returns "/myapp/"
# url_for "/foo" # Returns "/myapp/foo"
# url_for "/foo", :full # Returns "http://example.com/myapp/foo"
#--
# See README.rdoc for a list of some of the people who helped me clean
# up earlier versions of this code.
