[Gretl-devel] Accessing pdf manual via gretlcli

Dear all, from time to time I receive questions for some of my packages, and often direct people to the manual of the package first. In case the manual is written in the text format "help pckg-name" helps (even though I've experienced that this doesn't work for all packages). However, in case the manual is in pdf format this does not work. Is it be possible to open the pdf automatically if one types "help cointARDL" into gretlcli (take my own packg. as an example)? It seems that gretl newbies are not always aware of how to access the help file... Maybe this would make life easier. Best, Artur
