UID management

[Philipp Gühring]

Hi,

I am missing the GPGME manual on the website:
http://www.gnupg.org/(en)/documentation/manuals.html


Does GPGME have UID management functionality? 
I would need deluid to delete UIDs from keys, and I can´t find it in the 
documentation.


When I do gpg --with-colons $file then I get a list of UIDs in that file.
When I do a fresh gpg --import $file and then a gpg --edit-key $uid then I 
also get a list of those UIDs.
But that list is ordered differently.
Why is it ordered differently?
How are both lists ordered?


Best regards,
Philipp Gühring
