I use cvs gretl updated taday at noon on debian/jassie
What I have done to all textbooks datafiles and scripts worked properly from menu:
1 moved directories as shown
2 created >POE4data (as shown) and moved gdt files from /data to /POE4data
3 copied gdt files from data/stock_watson to /data and erased empty data/stock_watson
and POE4_scripts
Proposal: make different names for SW data and scripts directories inside gretl site archives
Make unpacking behavior the same for all textbooks data
Change reading directory for sample data files from /gretl to /gretl/data
