When a Koha script runs, it makes use of a certain number of things:
# Zconn
# A connection object for the Zebra server
-# Koha's main configuration file koha-conf.xml
-# is searched for according to this priority list:
-#
-# 1. Path supplied via use C4::Context '/path/to/koha-conf.xml'
-# 2. Path supplied in KOHA_CONF environment variable.
-# 3. Path supplied in INSTALLED_CONFIG_FNAME, as long
-# as value has changed from its default of
-# '__KOHA_CONF_DIR__/koha-conf.xml', as happens
-# when Koha is installed in 'standard' or 'single'
-# mode.
-# 4. Path supplied in CONFIG_FNAME.
-#
-# The first entry that refers to a readable file is used.
-
-use constant CONFIG_FNAME => "/etc/koha/koha-conf.xml";
- # Default config file, if none is specified
-
-my $INSTALLED_CONFIG_FNAME = '__KOHA_CONF_DIR__/koha-conf.xml';
- # path to config file set by installer
- # __KOHA_CONF_DIR__ is set by rewrite-confg.PL
- # when Koha is installed in 'standard' or 'single'
- # mode. If Koha was installed in 'dev' mode,
- # __KOHA_CONF_DIR__ is *not* rewritten; instead
- # developers should set the KOHA_CONF environment variable
-

-
-The simple elements nested within the <config> element:

-The <listen> elements:

-
-The elements nested within the <server> element:
-
- my $ccl2rpn = $koha->{'server'}->{'biblioserver'}->{'cql2rpn'};
-
-Returns undef in case of error.
