MrProjExt has exclusively been documented in English
First steps in developing the MrProjExt had been done in 2001. The initial version was published at the end of 2001. The last update followed in 2003. In 2004 I decided to close this project because of the introduction of planner as a replacement of mrproject.
The Mrproject Extractor
About the Idea of 'MrProjExt'
Although mrproject was a very ambitious eyecandy und intuitively usable project management tool (Yes, this is not a typo: for a moment I am talking about MrProject instead of MrProjext!), mrproject lacked some practically whished features concerning the reporting and the external use of the inserted data.
But mrpoject operated on an xml-file as database. Therefore it should be possible to extract the needed data out of that file. And that was the task of the MrProject-Extractor, named MrProjExt: The original Mrproject database acts as a masterfile out of which a smaller content are extracted.
