program. All the commands just end up calling <code>make</code> with appropriate
arguments. The intention was to allow preexisting packages that used
makefiles to be wrapped into Cabal packages. In practice essentially all
such packages were converted over to the "Simple" build system instead.
Consequently this module is not used much and it certainly only sees cursory
maintenance and no testing. Perhaps at some point we should stop pretending
that it works.
</p><p>Uses the parsed command-line from <a href="Distribution-Simple-Setup.html">Distribution.Simple.Setup</a> in order to build
Haskell tools using a backend build system based on make. Obviously we
assume that there is a configure script, and that after the ConfigCmd has
been run, there is a Makefile. Further assumptions:
</p><dl><dt>ConfigCmd</dt><dd> We assume the configure script accepts
<code>--with-hc</code>,
<code>--with-hc-pkg</code>,
<code>--prefix</code>,
<code>--bindir</code>,
<code>--libdir</code>,
<code>--libexecdir</code>,
<code>--datadir</code>.
</dd><dt>BuildCmd</dt><dd> We assume that the default Makefile target will build everything.
</dd><dt>InstallCmd</dt><dd> We assume there is an <code>install</code> target. Note that we assume that
this does *not* register the package!
</dd><dt>CopyCmd</dt><dd> We assume there is a <code>copy</code> target, and a variable <code>$(destdir)</code>.
The <code>copy</code> target should probably just invoke <code>make install</code>
recursively (e.g. <code>$(MAKE) install prefix=$(destdir)/$(prefix)
bindir=$(destdir)/$(bindir)</code>. The reason we can't invoke <code>make
install</code> directly here is that we don't know the value of <code>$(prefix)</code>.
</dd><dt>SDistCmd</dt><dd> We assume there is a <code>dist</code> target.
</dd><dt>RegisterCmd</dt><dd> We assume there is a <code>register</code> target and a variable <code>$(user)</code>.
</dd><dt>UnregisterCmd</dt><dd> We assume there is an <code>unregister</code> target.
</dd><dt>HaddockCmd</dt><dd> We assume there is a <code>docs</code> or <code>doc</code> target.

</p><p>An instance of <code><a href="../base-4.5.1.0/Data-Eq.html#t:Eq">Eq</a></code> is provided, which implements exact equality
modulo reordering of the tags in the <code><a href="Distribution-Make.html#v:versionTags">versionTags</a></code> field.
</p><p>An instance of <code><a href="../base-4.5.1.0/Data-Ord.html#t:Ord">Ord</a></code> is also provided, which gives lexicographic
ordering on the <code><a href="Distribution-Make.html#v:versionBranch">versionBranch</a></code> fields (i.e. 2.1 > 2.0, 1.2.3 > 1.2.2,
etc.). This is expected to be sufficient for many uses, but note that
you may need to use a more specific ordering for your versioning
scheme. For example, some versioning schemes may include pre-releases
which have tags <code>"pre1"</code>, <code>"pre2"</code>, and so on, and these would need to
be taken into account when determining ordering. In some cases, date
ordering may be more appropriate, so the application would have to
look for <code>date</code> tags in the <code><a href="Distribution-Make.html#v:versionTags">versionTags</a></code> field and compare those.
The bottom line is, don't always assume that <code><a href="../base-4.5.1.0/Data-Ord.html#v:compare">compare</a></code> and other <code><a href="../base-4.5.1.0/Data-Ord.html#t:Ord">Ord</a></code>
operations are the right thing for every <code><a href="Distribution-Make.html#t:Version">Version</a></code>.
</p><p>Similarly, concrete representations of versions may differ. One
possible concrete representation is provided (see <code><a href="../base-4.5.1.0/Data-Version.html#v:showVersion">showVersion</a></code> and
<code><a href="../base-4.5.1.0/Data-Version.html#v:parseVersion">parseVersion</a></code>), but depending on the application a different concrete
representation may be more appropriate.
