# If new section is added (as here I have also 'tmp' for fedorapeople.org)
# and the script has a symlink named as the section (so I have tmp as
# a symlink to this script) it saves the file to the location defined in
# such section when called under the other name.
# So, `tmp filename` saves file filename to fedorapeople for me.
