DOC_CONTENTS="
Please create one or more config files in
/etc/ez-ipupdate/. A bunch of samples can
be found in the doc directory.

All config files must have a '.conf' extension.

If you are using openRC you need to:
- Please do not use the 'run-as-user', 'run-as-euser',
'cache-file' and 'pidfile' options, since these are
handled internally by the init-script.

-If you want to use ez-ipupdate in daemon mode,
please add 'daemon' to the config file(s) and
add the ez-ipupdate init-script to the default runlevel.
Without the 'daemon' option, you can run the
init-script with the 'update' parameter inside
your PPP ip-up script.
