= Adding Configuration Selection Items

Example Configurations can be added to the Configuration Selector
by two methods:

* Auxiliary applications -- Applications installed independently
  with a deb package can place configuration subdirectories in
  a specified system directory.  The directory name is specified
  using the shell linuxcnc_var script:

====
  $ linuxcnc_var LINUXCNC_AUX_EXAMPLES
  /usr/share/linuxcnc/aux_examples
====

* Runtime settings -- the configuration selector can also offer
  configuration subdirectories specified at runtime using an
  exported environamental variable (LINUXCNC_AUX_CONFIGS).  This
  variable should be a path list of one or more configuration
  directories separated by a (:).  Typically, this variable
  would be set in a shell starting linuxcnc or in a user's
  ~/.profile startup script.  Example:

====
  export LINUXCNC_AUX_CONFIGS=~/myconfigs:/opt/otherconfigs
====
