137 When a Koha script runs, it makes use of a certain number of things:
138 configuration settings in F</etc/koha/koha-conf.xml>, a connection to the Koha
139 databases, and so forth. These things make up the I<context> in which
142 This module takes care of setting up the context for a script:
143 figuring out which configuration file to load, and loading it, opening
144 a connection to the right database, and so forth.
146 Most scripts will only use one context. They can simply have
152 Other scripts may need to use several contexts. For instance, if a
153 library has two databases, one for a certain collection, and the other
154 for everything else, it might be necessary for a script to use two
155 different contexts to search both databases. Such scripts should use
156 the C<&set_context> and C<&restore_context> functions, below.
158 By default, C4::Context reads the configuration from
159 F</etc/koha/koha-conf.xml>. This may be overridden by setting the C<$KOHA_CONF>
160 environment variable to the pathname of a configuration file to use.
167 # In addition to what is said in the POD above, a Context object is a
168 # reference-to-hash with the following fields:

173 # file (/etc/koha/koha-conf.xml).

216 structure is a bit complex to the uninitiated ... take a look at the
217 koha-conf.xml file as well as the XML::Simple documentation for details. Or,
218 here are a few examples that may give you what you need:
