[Zope-Checkins] CVS: Zope3/lib/python/Zope/TAL - talgettext.py:1.2

[Barry Warsaw]

Update of /cvs-repository/Zope3/lib/python/Zope/TAL
In directory cvs.zope.org:/tmp/cvs-serv24366/lib/python/Zope/TAL

Modified Files:
	talgettext.py 
Log Message:
Get rid of the -o/--output switch (just use shell i/o redirection for
now).

Handle multiple files specified on the command line so that we can
combine all msgid's in a single .po file.  Add a POEngine which
contains a `catalog' of all the msgids seen.


=== Zope3/lib/python/Zope/TAL/talgettext.py 1.1 => 1.2 ===
 this program to extract GNU gettext .po file entries.
