by standard applications with no built-in support for WebDAV, such as the GNU
coreutils (@command{cp}, @command{mv}, etc.) or a graphical word processor.

Davfs2 works with most WebDAV servers with no or little configuration.  It
supports TLS (HTTPS), HTTP proxies, HTTP basic and digest authentication, and
client certificates.  It performs extensive caching to avoid unnecessary network
traffic, stay responsive even over slow or unreliable connections, and prevent
data loss.  It aims to make use by unprivileged users as easy and secure as
possible.

However, davfs2 is not a full-featured WebDAV client.  The file system interface
and the WebDAV protocol are quite different.  Translating between the two is not
always possible.")

     "TMSU is a tool for tagging your files.  It provides a simple
command-line utility for applying tags and a virtual filesystem to give you a
tag-based view of your files from any other program.  TMSU does not alter your
files in any way: they remain unchanged on disk, or on the network, wherever
your put them.  TMSU maintains its own database and you simply gain an
additional view, which you can mount where you like, based upon the tags you
set up.")
