No longer supported: as of version 1.9.10 (RC1) released in late June 2012, OpenLP includes a ZionWorx importer. That supersedes this utility so it is no longer supported.
Latest version: ZionWorx Export 0.62 (18 April 2012)
It converts a proprietary ZionWorx songs TurboDB database to individual OpenLyrics files which can be read by OpenLP 2.0 and other software. The utility uses dataWeb's command-line TurboDB Data Exchange tool to extract the song data from ZionWorx, and then massages it into OpenLyrics format.
Hope it's useful to someone. Any bugs or comments, sing out!
