Yes, but if we are in a multi-user environment, and we want one
installation to be used by multiple users, then this problems prevents
it: only the user which installed the software can actually use
it. When a user is running forrest to build a web site, it should not
need to write anything to the installation directory: all intermediate
and final files should be written in the build directory, or at least
this is what I would expect.

Besides, I have discovered another (minor) problem which might surface
in a multi-user environment. If a user is trying to run forrest
through a rlogin/ssh connection in a remote machine, this might be
difficult because the conversion of svg images seems to require
access to the X server. The workaround is to grant access to the X
server on the machine where forrest is being run (xhost +) and set the
DISPLAY variable to the remote machine's display. See below the error
message that I get when I try to run it remotely (without correct X
settings):

None of these problems actually prevents me from using Forrest, but I
though it might be good to report them.
