+<a class="ulink" href="overview.asciidoc" target="_top">many features</a>? This chapter will
+attempt to answer that.</p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_erlang_mk_is_fast"></a>23.1. Erlang.mk is fast</h2></div></div></div><p>Erlang.mk is as fast as it gets.</p><p>Erlang.mk will group the compilation of files so as to avoid
+running the BEAM more than necessary. This saves many seconds
+compared to traditional Makefiles, even on small projects.</p><p>Erlang.mk will not try to be too smart. It provides a simple
+solution that works for most people, and gives additional
+options for projects that run into edge cases, often in the
+form of extra variables or rules to be defined.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_erlang_mk_gives_you_the_full_power_of_unix"></a>23.2. Erlang.mk gives you the full power of Unix</h2></div></div></div><p>Erlang.mk is a Makefile.</p><p>You could use Erlang.mk directly without configuring anything
+and it would just work. But you can also extend it greatly
+either through configuration or hooks, and you can of course
+add your own rules to the Makefile.</p><p>In all cases: for configuration, hooks or custom rules, you
+have all the power of Unix at your disposal, and can call
+any utility <span class="emphasis"><em>or even any language interpreter</em></span> you want,
+every time you need to. Erlang.mk also allows you to write
+scripts in this small language called Erlang directly inside
+your Makefile if you ever need to…</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_erlang_mk_is_a_text_file"></a>23.3. Erlang.mk is a text file</h2></div></div></div><p>Erlang.mk is a Makefile.</p><p>Which means Erlang.mk is a simple text file. You can edit a
+text file. Nothing stops you. If you run into any bug, or
+behavior that does not suit you, you can just open the
+<span class="emphasis"><em>erlang.mk</em></span> file in your favorite editor, fix and/or comment
+a few lines, save, and try again. It’s as simple as it gets.</p><p>Currently using a binary build tool? Good luck with that.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_erlang_mk_can_manage_erlang_itself"></a>23.4. Erlang.mk can manage Erlang itself</h2></div></div></div><p>Erlang.mk isn’t written in Erlang.</p><p>That’s not a good thing, you say? Well, here’s one thing
+that Erlang.mk and Makefiles can do for you that Erlang
+build tool can’t easily: choose what version of Erlang is
+to be used for compiling the project.</p><p>This really is a one-liner in Erlang.mk (a few more lines
+if you also let it download and build Erlang directly)
+and allows for even greater things, like testing your
+project across all supported Erlang versions in one small
+command: <code class="literal">make -k ci</code>.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_erlang_mk_can_do_more_than_erlang"></a>23.5. Erlang.mk can do more than Erlang</h2></div></div></div><p>Erlang.mk doesn’t care what your dependencies are written in.</p><p>Erlang.mk will happily compile any dependency, as long as
+they come with a Makefile. The dependency can be written
+in C, C++ or even Javascript… Who cares, really? If you
+need Erlang.mk to fetch it, then Erlang.mk will fetch it
+and compile it as needed.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_erlang_mk_integrates_nicely_in_make_and_automake_projects"></a>23.6. Erlang.mk integrates nicely in Make and Automake projects</h2></div></div></div><p>If you are planning to put your project in the middle of
+a Make or Automake-based build environment, then the most
+logical thing to do is to use a Makefile.</p><p>Erlang.mk will happily sit in such an environment and behave
+as you expect it to.</p></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="pt05.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="pt05.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch24.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top"> </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> </td></tr></table></div>
