Initial support to freeze turbogears.

The zip library used by cx_freeze and py2exe does not support egg. The resource_filename is not supported in plain zip.

The idea looks good, but I'm not totally confident with the way the temporary directory is created. Maybe it should be better to rely on pkg_resources.get_default_cache(). Will it provide a reliable directory which we can avoid checking and creating ourselves?

Also as the temporary file path is created joining os.path.join(self.__temp_dir, basename) shouldn't it lead to collisions? If there are two packages with edit template they will end up overwriting one with the other. Instead of using the executable+basename wouldn't it be more reliable to use the full package path?

My two cents, but as we are messing with the user file system I want to ensure it's as reliable as possible :D

The change of tempfile.gettempdir() to get_default_cache() is identical, it will become a temporary directory as the same manner. Before, the extract files is in %temp%. With default_cache(), the directory is %appdata%\Python-Eggs, in my case. And, get_default_cache() does not create the directory and its subdirectories. In egg packages the directories will be created by resource_filename, but in zip, resource_filename is not supported/implemented.

About the collisions, I imagined a rare case, but...

A new request will be send.

I have a few questions to complete this task, which are closely related to how tg was made. Can I ask you a few things as problems arise? What is the best way? By email? The group?

So to advance. Making this change to the code, I managed to import the templates, except the "master.html". I had to use an ugly hack to continue testing. See the hack:

if getattr(sys, 'frozen', False):
    dotted_filename_finder = base_config['tg.app_globals']['dotted_filename_finder']
    dotted_filename_finder.get_dotted_filename(base_config.package_name+'.templates.master')
