=head1 DESCRIPTION
When a Koha script runs, it makes use of a certain number of things:
-configuration settings in F</etc/koha.xml>, a connection to the Koha
+configuration settings in F</etc/koha/koha-conf.xml>, a connection to the Koha
databases, and so forth. These things make up the I<context> in which
the script runs.
the C<&set_context> and C<&restore_context> functions, below.
By default, C4::Context reads the configuration from
-F</etc/koha.xml>. This may be overridden by setting the C<$KOHA_CONF>
+F</etc/koha/koha-conf.xml>. This may be overridden by setting the C<$KOHA_CONF>
environment variable to the pathname of a configuration file to use.

# A reference-to-hash whose keys and values are the

# A handle to the appropriate database for this context.

+# 3. Path supplied in INSTALLED_CONFIG_FNAME, as long

structure is a bit complex to the uninitiated ... take a look at the
