[Rpm-maint] OR'ed dependency check

[Alex Lobanovsky]

Thank you!
The link to the manual is great!

I understood the idea of these "virtual provides". It works fine unless you
have no sources of the packages you would require.
Then I'm completely dependent on sanity and common sense of other developers
- if they add _common_ "provides" strings.

In my case, I need to
Requires: wine OR wine-core AND wine-ldap
Unfortunately, wine, wine-core and wine-ldap do no share same provide
strings (except for huge list of various .so's, but I don't think it's a
good idea to rely on list of libraries).


Thank you again for the support!

Kind regards,
Alex
