[librecat-dev] Catmandu and general csv manipulation use case example

[Rolschewski, Johann]

Hi,

sorry, but this is a discussion list for the Catmandu project and not the "provide a solution for each of my tasks" list. Please get familiar with the basics of Catmandu. I also expect that you show what you have tried to solve your task with Catmandu before I will answer any further questions. And please stop switching your email address.

Johann
