Rex::Helper::Rexfile::ParamLookup \- A command to manage task parameters.
.PP
A command to manage task parameters. Additionally it register the parameters as template values.
.PP
This module also looks inside a CMDB (if present) for a valid key.

First \fIparam_lookup\fR checks the task parameters for a valid parameter. If none is found and if a \s-1CMDB\s0 is used, it will look inside the cmdb.
.PP
If your module is named \*(L"Rex::NTP\*(R" than it will first look if the key \*(L"Rex::NTP::param_name\*(R" exists. If it doesn't exists it checks for the key \*(L"param_name\*(R".
