I use /usr/lib/myapp for static beam files etc, and /var/lib/myapp for 
variable state information like mnesia databases etc.

Run lintian manually and use "--info" as command line parameter. Then 
each error will be explained.

I suppose it's for Microsoft's operating systems. There is no need to 
install them I guess.

If you need to install your own copy of beam it needs to be linked 
against the system libraries, otherwise you will face problems if for 
example security vulnerabilities are found in the embedded libraries.

Refer to "lintian --info"E: myapp: dir-or-file-in-opt opt/myapp/
> E: myapp: dir-or-file-in-opt opt/myapp/bin/

Consider using /usr/lib/myapp instead.
