Subject: Added Content module for pointing to another Evergreen instance
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=d806ff5dec075d7cbf3fb15cb90960c78e362f56;p=evergreen%2Ftadl.git

Added Content module for pointing to another Evergreen instance

Needs tweaks to opensrf.xml, for example:

        <added_content>
            <!-- load the OpenLibrary added content module -->
            <module>OpenILS::WWW::AddedContent::Evergreen</module>
            <base_url>http://grpl.michiganevergreen.org/opac/extras/ac</base_url>
