Probably it's only my ignorance , but when i get the TAGS file for emacs recursing the directories when i installed Zope2 eggified,
ctags raise this 2 warning about 2 files. No idea why. All other py files are parsed ok.
~/opt/lib/python2.6/site-packages-testing$ ctags -e --recurse --languages=python .
ctags: Warning: ignoring null tag in Zope2-2.13.1-py2.6.egg/OFS/Cache.py
ctags: Warning: ignoring null tag in ZODB3-3.10.1-py2.6-linux-i686.egg/ZODB/scripts/fsstats.py
I tried -x option
ctags -e --languages=python --verbose -x Cache.py
and things doesn't look too bad but anyway, how could i find out which token is raising this warnings ?
