Subject: Make stylesheet file name parametric
X-Git-Tag: v0.1~29
X-Git-Url: https://git.ao2.it/tweeper.git/commitdiff_plain/ef4f6c6fb10b121fa79a0d8b6ccd7930fec48591?ds=sidebyside;hp=-c

Make stylesheet file name parametric

The host is encoded in the file name, this is in order to support more
sites with no changes to the code, all that is needed is just new
stylesheets with the host in their filename following the scheme will:

  rss_converter_HOST.xsl

Where HOST has the meaning of the "host" field in the return value of
the PHP parse_url() function.
