2551143: Problem with installing external trackers ... the change from distutils to setuptools moved the directories for the templates, man pages and docs under the install directory. The install directory is buried in the directory tree under /usr/ib/python/.../roundup...egg/... This patch tries to put them under: the directory specified by --prefix argument the python platform library prefix that prefixes /lib in sysconfig.getpath('platlib') the directory returned by sys.prefix.

try:
    from html import escape as html_escape_  # python 3

    def html_escape(str, quote=False):
        # html_escape under python 3 sets quote to true by default
        # make it python 2 compatible
        return html_escape_(str, quote=quote)
except ImportError:
    # python 2 fallback
    from cgi import escape as html_escape  # noqa: F401
