#### 7.2.123 set-emodule-path

`(set-emodule-path (PATH1 ... PATHN))`
  Sets the search path for external modules. The PATHi should be pathnames of directories containing, for each module, the module's executable file and a .geomview-<modulename> file which contains an (emodule-define ...) command for that module. This command implicitly calls (rehash-emodule-path) to rebuild the application browser from the new path setting. The special directory name `+` is replaced by the existing path, so e.g. (set-emodule-path (mydir +)) prepends mydir to the path.
