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