Zip export format support (additionaly to .tar.gz)

Use the autolocale module to import lots of po files. For tar files use 7zip.

Thanks, I know it. Only two reasons:
1) 1 file .po is much more convenient than 10 (20...)
2) Archive Zip by default works in windows, and for gzip(tar) is necessary rar, 7zip, etc.

1. How many po files is more convinient is a good question. Some people say it is much easier to get over smaller files (ie. easier to set expectations / targets), and then import them back in. Also Drupal is much happier with smaller files to import.

2. All Drupal modules and themes are distributed with tar.gz, so it is expected that you have some program to handle these.

1) i think if you use autolocale (d5) or d6 you shouldn't 'make' this question. It will be Drupal that will import po files for you, isnt'it? A additional option create more confusion.

2) tar.gz is the right answer, imho. If you manage a drupal site, you extracted tar.gz. I agree with Gàbor.

2 Psicomante: My friends establish drupal and is frequent they even badly know css & html :-). Windows - is windows...
I do not insist, but the alternative is always useful

then....i don't know. Pvasili, you're right too, perhaps Gàbor make the rightest choice :)

Note that we cannot change how Drupal itself as well as modules and themes are packaged, so they would still need to go through these hoops anyway. Also, again, I said we need a decent zip library. Currently, the code depends on the PEAR Tar library to do the tar.gz files, but in fact it would be better if we could live without such external dependencies.

As long as Drupal.org does not provide such a format (and there seems to be no sign to that), we'll not do this either.
