5.4.4.1 Examples for path settings
[Permitted Paths]
read=%INSTALLDIR%
would permit reading from the directory where the POV-Ray supplementary files are installed.
Note that the installdir location does not relate to where the binary is run from - it relates to the information
defined at compile-time. Relative paths are legal as well, and will be resolved only once at load time (but relative
to the current directory, not the installdir). For example, a relative path like the following ...
[Permitted Paths]
read+write=../output
would be resolved with relation to the current directory at the time POV-Ray for Unix was started, so if
you started povray while in the directory ~/myscenes/newscene , then the above path would be resolved as ~/myscenes/output .
Please note that the actual location of the povray binary is not relevent here - it is the current directory that
matters (which is typically not that of the program).
