I can easily read e00 files with QGIS and it seems as if in older versions of ogr there was driver support for the arc/info e00 file format. Nowadays that seems to be deprecated, as running
ogrinfo --formats doesn't list arc/info.
I also found this useful link, a general description of the file format. Based on that information I would be able to write my own program to put all the pieces together. But hey, this must have been done before, right?
Can somebody point me into the right direction?
