HiddenEnvVars=envlist
This
variable contains the comma-separated list of environment variables that will be
hidden, i.e. author will not be able to use $wbe
function with those variables.
Default value is *, what means that all environment
variables will be hidden. However, some of the environment variables are very
important for developing advanced WBSP-powered sites, so it is good idea to hide
only those environment variables that can be abused (e.g. PATH, COMP*, SYSTEM*,
etc.)
