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

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

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