After installing ExUtils-F77: > Look at the man pages for f77 and make: > man f77 > To find out how to use them. man f77 replied: Code: No manual entry for f77 (the same for F77). There is a file Code: /usr/share/man/man3/ExtUtils::F77.3pm.gz It it contains man F77, then how I can correctly extract it? Thank you in advance. PS Please also tell advice, if this is offtopic, I will stop.
