Packages may customize the components
that comprise Pex.
A path package is only active during the execution and monitoring of a particular execution path. Packages are installed by special attributes that decorate test generators
. They are designed to execute some code when Pex' path components are loaded, and before and after the execution path is execution.
See the DumpSolutionAttribute
class in the Samples.Pex
for an example of path package.
