In many preprocessing steps we are using many macros that specify many things, from urls to user name, passwords etc.

When using the zabbix_js to "debug" and test the script, the macro must be replaced with the value of the macro, and then replaced back to be used in the preprocess steps, with possible errors.

It will be nice to specify a file with the macro values, something like "-M file" and file being
{$MACRONAME}=myvalue
