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

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

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