When I chose File->Open data->Sample file and press "Look on server"
button and install, for example, ashenfelter (small letter for option name, not for prof.
Ashenfelter), directory ~/gretl/data/ashenfelter/ is created. When I restart Gretl
"Ashenfelter" option doesn't appear in "gretl: data files" window
as it should be. I resolve this problem by manually moving /ashenfelter to
~/gretl/ashenfelter/ The same with the other samples but for POE 4th. The files.gdt for
POE4 are created in ~/data/ without forming POE4data directory. Some small changes are
needed to unarchiving parameters, or, alternatively to reading paths to sample files
