.Sh DESCRIPTION
Netcache is a command-line tool to retrieve,
cache and access networked content.
By default,
netcache will returns a cached version of a given URL,
downloading it only if a cache version doesn't exist.
A validity duration,
in seconds,
can also be given
so netcache downloads the content
only if the existing cache is older than the validity.
