creating gedcom files from scratch and more...

I am new the perl gedcom; but wrote a genealogy 'HyperCard Stack" in  
1988
and later ported the data to MySql and a web GUI.

So I have two things I want to do:

1) export my data into gedcom file(s), and

2) Import .ged files into my system.

I think the import should be easy; but in trying to write the export
I don't know how to map my event items (Birth, Death, etc). to

	$i1->add("christening date",

calls. What are the complete set of types like "christening date,"
"birth date', etc? Where are these documented?

Can I be processing two individuals at a time?
I.e. I am building the husband and wite gedcom information
and I want to add a note; but the add_note doesn't
require an individual (e.g. $i1 or $i2) to apply the note to.

I'm sure these are obvious question, once I know the system
better.

Is there a comprehensive example of how to create a complex
.ged record for a family?

Thanks in advance.
