78: =head1 SYNOPSIS
79:

81: use LONCAPA::Configuration;

85: =head1 DESCRIPTION
86:
1.4 harris41 87: Many different parts of the LON-CAPA software need to read in the
88: machine-specific configuration information. These included scripts
89: controlling the TCP/IP layer (e.g. F<lonc> and F<lond>), testing scripts
90: (e.g. test_weblayer.pl and sqltest.pl), and utility scripts
91: (e.g. clusterstatus.pl and metadata_keywords.pl).
1.1 harris41 92:
93: The following methods are available:
94:
95: =over 4
96:
97: =item $perlvarref = LONCAPA::Configuration::read_conf( @filename_list );
98:
99: On a typical LON-CAPA server, the filename list argument will consist of
100: just one element, "loncapa.conf".
101:
102: If there are multiple elements within the filename list, then these
103: filenames are processed consecutively.
104:
105: A hash reference is returned and consists of those values which
106: have been initialized from the configuration filenames indicated
107: in the arguments.
108:
109: If multiple file names define the same hash key, then priority is
1.4 harris41 110: given toward the B<last> file name processed.
