130 When a Koha script runs, it makes use of a certain number of things:
131 configuration settings in F</etc/koha/koha-conf.xml>, a connection to the Koha
132 databases, and so forth. These things make up the I<context> in which
135 This module takes care of setting up the context for a script:
136 figuring out which configuration file to load, and loading it, opening
137 a connection to the right database, and so forth.
139 Most scripts will only use one context. They can simply have
145 Other scripts may need to use several contexts. For instance, if a
146 library has two databases, one for a certain collection, and the other
147 for everything else, it might be necessary for a script to use two
148 different contexts to search both databases. Such scripts should use
149 the C<&set_context> and C<&restore_context> functions, below.
151 By default, C4::Context reads the configuration from
152 F</etc/koha/koha-conf.xml>. This may be overridden by setting the C<$KOHA_CONF>
153 environment variable to the pathname of a configuration file to use.

161 # reference-to-hash with the following fields:

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