programs. A <code><a href="Distribution-Simple-Program.html#t:Program">Program</a></code> is a static notion of a known program. A
<code><a href="Distribution-Simple-Program.html#t:ConfiguredProgram">ConfiguredProgram</a></code> is a <code><a href="Distribution-Simple-Program.html#t:Program">Program</a></code> that has been found on the current
machine and is ready to be run (possibly with some user-supplied default
args). Configuring a program involves finding its location and if necessary
finding its version. There is also a <code><a href="Distribution-Simple-Program.html#t:ProgramDb">ProgramDb</a></code> type which holds
configured and not-yet configured programs. It is the parameter to lots of
actions elsewhere in Cabal that need to look up and run programs. If we had
a Cabal monad, the <code><a href="Distribution-Simple-Program.html#t:ProgramDb">ProgramDb</a></code> would probably be a reader or
state component of it.</p><p>The module also defines all the known built-in <code><a href="Distribution-Simple-Program.html#t:Program">Program</a></code>s and the
<code><a href="Distribution-Simple-Program.html#v:defaultProgramDb">defaultProgramDb</a></code> which contains them all.</p><p>One nice thing about using it is that any program that is
registered with Cabal will get some "configure" and ".cabal"
helpers like --with-foo-args --foo-path= and extra-foo-args.</p><p>There's also good default behavior for trying to find "foo" in
PATH, being able to override its location, etc.</p><p>There's also a hook for adding programs in a Setup.lhs script. See
hookedPrograms in <code><a href="Distribution-Simple.html#v:UserHooks">UserHooks</a></code>. This gives a
hook user the ability to get the above flags and such so that they
don't have to write all the PATH logic inside Setup.lhs.</p></div></div><div id="synopsis"><p id="control.syn" class="caption expander" onclick="toggleSection('syn')">Synopsis</p><ul id="section.syn"
