NEW! you can install via cpan: https://metacpan.org/release/PACMAN/Acme-CatFS-0.001

1. you should install LWP::Simple and Fuse:Simple - use cpan or cpanm
2. you should configure the local fuse install to run as root or as common user
3. don't forget 'fusermount -u <mountpoint>' after finish the script

to install dependencies

you can use regular cpan OR cpanminus ( http://search.cpan.org/~miyagawa/App-cpanminus-1.7001/lib/App/cpanminus.pm )

$ cpan LWP::Simple
$ cpan Fuse:Simple  ( maybe you need install via apt-get libfuse-dev too )

the difference is: cpanminus is more indicate if you want install something without change the default perl instalation in your operational system. 90% of the cases you can install with regular cpan ( built in ).

to test

$ chmod +x cats.pl
$ mkdir catfs
$ ./cats.pl catfs

# in other terminal 

$ ls catfs
cat.jpg

$ gimp catfs/cat.jpg  # will open a different kitten pic each time

# after finish the script
$ fusermount -u catfs
