<p>The <em>Tools</em> application contains a number of stand-alone
tools, which are useful when developing Erlang programs.</p>
<taglist>
<tag><em>cover</em></tag>
<item>A coverage analysis tool for Erlang.</item>
<tag><em>cprof</em></tag>
<item>A profiling tool that shows how many
times each function is called. Uses a kind of local call trace
breakpoints containing counters to achieve very low runtime
performance degradation.</item>
<tag><em>emacs - (erlang.el and erlang-start.el)</em></tag>
<item>This package provides support
for the programming language Erlang in Emacs. The package provides an
editing mode with lots of bells and whistles, compilation
support, and it makes it possible for the user to start Erlang
shells that run inside Emacs.</item>
<tag><em>eprof</em></tag>
<item>A time profiling tool; measure how time is used in Erlang
programs. Erlang programs. Predecessor of <em>fprof</em> (see below).</item>
<tag><em>fprof</em></tag>
<item>Another Erlang profiler; measure how time is used in your
Erlang programs. Uses trace to file to minimize runtime
performance impact, and displays time for calling and called
functions.</item>
<tag><em>instrument</em></tag>
<item>Utility functions for obtaining and analysing resource usage
in an instrumented Erlang runtime system.</item>
<tag><em>lcnt</em></tag>
<item>A lock profiling tool for the Erlang runtime system.</item>
<tag><em>make</em></tag>
<item>A make utility for Erlang similar to UNIX make.</item>
<tag><em>tags</em></tag>
<item>A tool for generating Emacs TAGS files from Erlang source
files.</item>
<tag><em>xref</em></tag>
<item>A cross reference tool. Can be used to check dependencies
between functions, modules, applications and releases.</item>
