<sect3 id='package-ebuild-helper-functions-output-ebegin'>
<title>ebegin</title>
<para>
Like einfo, we output a helpful message and then hint that the following
operation may take some time to complete. Once the task is finished, you
need to call eend.
</para>
</sect3>
<sect3 id='package-ebuild-helper-functions-output-eend'>
<title>eend</title>
<para>
Followup the ebegin message with an appropriate "OK" or "!!" (for errors)
marker. If status is non-zero, then the additional error message is
displayed.
</para>
</sect3>
<sect3 id='package-ebuild-helper-functions-output-einfo'>
<title>einfo</title>
<para>
Same as elog, but should be used when the message isn't important
to the user (like progress or status messages during the build process).
</para>
</sect3>
<sect3 id='package-ebuild-helper-functions-output-elog'>
<title>elog</title>
<para>
If you need to display a message that you wish the user to read
and take notice of, then use elog. It works just like echo(1),
but adds a little more to the output so as to catch the user's eye.
The message will also be logged by portage for later review.
</para>
</sect3>
<sect3 id='package-ebuild-helper-functions-output-eqawarn'>
<title>eqawarn</title>
<para>
Same as einfo, but should be used when showing a QA warning to the user.
</para>
</sect3>
<sect3 id='package-ebuild-helper-functions-output-ewarn'>
<title>ewarn</title>
<para>
Same as einfo, but should be used when showing a warning to the user.
