So, decorator lines start with an '@'.  Source files end in '.py'.

Pseudo code could be:
----
initialize result container

with each sourcefilename in globbed list:
   for eachline in opened(sourcefilename):
     if line.startswith('@'):
       append [sourcefilename, line] to result

# print it

for eachline in result:
   print eachline
----

Hope this gets you going,
