Most Integrationsmethods imply that the wrapper binary is in a predefined location in respect to wrapper.conf configuration file or other application files. This means with WRAPPER_BIN_DIR could all such files could be located.
But to simplify a integration method where the wrapper (binary) files are at an independent location and only the wrapper.conf file is with the application it would be useful to have an WRAPPER_CONF_DIR predefined environment variable which can be used to locate the wrapper.conf directory and so the application without having the directory explicitly configured in the wrapper.conf
Please add such a variable which is set at startup of the wrapper to the path of the used wrapper.conf file.
It would be also useful, if this variable could be used early at startup in "#include" statements
