113 When a Koha script runs, it makes use of a certain number of things:
114 configuration settings in F</etc/koha/koha-conf.xml>, a connection to the Koha
115 databases, and so forth. These things make up the I<context> in which
118 This module takes care of setting up the context for a script:
119 figuring out which configuration file to load, and loading it, opening
120 a connection to the right database, and so forth.
122 Most scripts will only use one context. They can simply have
128 Other scripts may need to use several contexts. For instance, if a
129 library has two databases, one for a certain collection, and the other
130 for everything else, it might be necessary for a script to use two
131 different contexts to search both databases. Such scripts should use
132 the C<&set_context> and C<&restore_context> functions, below.
134 By default, C4::Context reads the configuration from
135 F</etc/koha/koha-conf.xml>. This may be overridden by setting the C<$KOHA_CONF>
136 environment variable to the pathname of a configuration file to use.
143 # In addition to what is said in the POD above, a Context object is a
144 # reference-to-hash with the following fields:
147 # A reference-to-hash whose keys and values are the
148 # configuration variables and values specified in the config
149 # file (/etc/koha/koha-conf.xml).
151 # A handle to the appropriate database for this context.
