Detailed Description

Container of Solvable providing a Capability (read only).

* Capability cap("amarok < 1.13");
*
* WhatProvides q( cap );
* Solvable firstMatch;
*
* if ( ! q.empty() )
* {
*   cout << "Found " << q.size() << " matches for " << cap << ":" << endl;
*   firstMatch = *q.begin();
*
*   for_( it, q.begin(), q.end() )
*     cout << *it << endl;
* }
*
* if ( firstMatch )
* {
*   WhatProvides req( firstMatch.requires() );
*   if ( ! req.empty() )
*   {
*      cout << "Found " << req.size() << " items providing requirements of " << firstMatch << ":" << endl;
*   }
* }
* 

Note: Note that there are capabilities which are not provided by any Solvable, but are system properties. For example:
* rpmlib(PayloadIsBzip2) <= 3.0.5-1

*

In that case a Solvable::noSolvable is returned, which has isSystem set true, although there should never be a Solvable::noSolvable returned with isSystem set false. If so, please file a bugreport.
* WhatProvides q( Capability("rpmlib(PayloadIsBzip2) <= 3.0.5-1") );

* for_( it, q.begin(), q.end() )

* {

* if ( *it )

* cout << "Capability is provided by package " << *it << endl;

* else if ( it->isSystem() )

* cout << "Capability is a system property" << endl;

* else

* ; // never reaching this \c else

* }
