Natural Selection
<footnote><para>Naturally Supervised Learning Email Classification Tool Interface Outline</para></footnote>
is a simple gui to <application>Select</application> for the mail component of <ulink url="http://www.ximian.com/apps/evolution.php3"><application>Evolution</application></ulink>.
It is only meant as an example of how classification could be used in a
mail user agent and the code is very experimental.

<title>Installation</title>

<para>
Natural Selection is provided as a patch, which means that you have to compile Evolution yourself to test it.
The patch is made against some version of the <application>Evolution</application> CVS.
</para>

<para>
To compile type the following commands:
<screen><prompt>$</prompt> <userinput>cd /path/to/evolution</userinput>
<prompt>$</prompt> <userinput>patch -p0 &lt; /path/to/select/evolution/natural-selection-*.diff</userinput>
</screen>
Then make Evolution as usual.

<title>Usage</title>

<para>
As mentioned, this is only provided as an example and is very experimental.
Therefore it does not do very much yet.
</para>

<note>
<para>
Remember that <application>selectd</application> have to be running for this to work.

<para>
To start the classifier interface you need to move one message from the inbox to some other folder (this is of course only a temporary solution).
If the classifier database is empty when you do this then it should try to learn all local folders.

Then when you select a message in the inbox, it should show a toolbar above the message preview, with some (by default up to three) buttons with the names of the folders that Select finds matches the message best.
Pushing one of these buttons will move the message into the corresponding folder.
