Return true if the solvable is installed on the system.

other package that has a different name.
+Reason constants
+

+The package status did not change as it was not related to any job.
+
+*SOLVER_REASON_UNIT_RULE*::
+The package was installed/erased/kept because of a unit rule, i.e. a rule
+where all literals but one were false.
+
+*SOLVER_REASON_KEEP_INSTALLED*::
+The package was chosen when trying to keep as many packages installed as
+possible.
+

+The decision happened to fulfill a job rule.
+
+*SOLVER_REASON_UPDATE_INSTALLED*::
+The decision happened to fulfill a package update request.
+
+*SOLVER_REASON_CLEANDEPS_ERASE*::
+The package was erased when cleaning up dependencies from other erased
+packages.
+
+*SOLVER_REASON_RESOLVE*::
+The package was installed to fulfill package dependencies.
+
+*SOLVER_REASON_WEAKDEP*::
+The package was installed because of a weak dependency (Recommends or

+The decision about the package was made when deciding the fate of orphaned

Set/get a solver specific flag. The flags define the policies the solver has
to obey. The flags are explained in the CONSTANTS section of this class.

interfaces that show both the job result and the problems.

+ (reason, rule) = solver.describe_decision(solvable)

+
+Return the reason why a specific solvable was installed or erased. For most of
+the reasons the rule that triggered the decision is also returned.

The Problem Class
-----------------
Problems are the way of the solver to interact with the user. You can simply list
Lookup functions. Note that the returned Ids are always translated into
the Ids of the global pool even if the repodata area contains its own pool.
