+<para>
+Every successful access is logged in a file called
+<filename>~hg/repos/<replaceable>repository</replaceable>/.hg/mercurial-server.log</filename>. This file is in YAML format for easy parsing, but if you don't like YAML, simply treat each line as a JSON data structure prepended with <code>- </code>. The log records the time as a
+UTC ISO 8601 time, the operation ("push" or "pull"), the path to the key as
+used in the access rules, the SSH connection information (including the source IP address), and the hex changeset IDs.

+For security reasons, all mercurial-server code runs as the <systemitem
+class="username">hg</systemitem> user.  The first thing this code reads when it starts is <filename>~hg/.mercurial-server</filename>; if this file is absent or corrupt the code won't run.  This file specifies all of the file paths that mercurial-server uses.  In particular, it specifies that mercurial-server always uses <code>HGRCPATH = /etc/mercurial-server/remote-hgrc.d</code> for remote operations, overriding any system <code>HGRCPATH</code>.

+<para>
+By creating such a file with suitable entries, you can run mercurial-server as a user other than <systemitem
+class="username">hg</systemitem>, or install it without root privileges; however I strongly recommend that if you need to do this, you use a user account that is used for no other purpose, and take the time to thoroughly understand how mercurial-server works before you attempt it.
