<a name="line-9"></a><span class='hs-comment'>-- This provides an abstraction which deals with configuring and running</span>

<a name="line-11"></a><span class='hs-comment'>-- 'ConfiguredProgram' is a 'Program' that has been found on the current</span>
<a name="line-12"></a><span class='hs-comment'>-- machine and is ready to be run (possibly with some user-supplied default</span>
<a name="line-13"></a><span class='hs-comment'>-- args). Configuring a program involves finding its location and if necessary</span>
<a name="line-14"></a><span class='hs-comment'>-- finding its version. There is also a 'ProgramConfiguration' type which holds</span>
<a name="line-15"></a><span class='hs-comment'>-- configured and not-yet configured programs. It is the parameter to lots of</span>
<a name="line-16"></a><span class='hs-comment'>-- actions elsewhere in Cabal that need to look up and run programs. If we had</span>
<a name="line-17"></a><span class='hs-comment'>-- a Cabal monad, the 'ProgramConfiguration' would probably be a reader or</span>
