libssl, libxml (Gnome not expat) are required. While it's nice that you 
provide the Cygwin dist as binaries it would be nicer to have a note of the 
necesary Cygwin components. Installation shouldn't be a rite of passage.

I'd kind of figured this out. I've looked a bit at the sources. Eek! c, 
perl, php and Python... what a mix! I wasn't expecting the Spanish 
inquisition! ;-) Is the stuff in "/contrib" examples?

C isn't my specialty but I think I understand what dlr.* does: creates and 
updates DLR records for msgs to individual MSISDNs. This makes sense and 
seems reasonable.

What I still don't quite get is is how "dlrurl" is supposed to work: if it 
is part of the gateway it would seem unnecessary to have it as a parameter 
as if it's external URL/URI but on the other hand as an external URL I 
would expect to be able to pass it user-definable parameters, ie. allow 
external users to track their own messages even without access to the DLR 
store.

ie.
if I have a call like this:
http://mysmsgateway.com:13013/cgi-bin/sendsms?username=****&to=004917878262267&mclass=2&text=hm&password=******
validity=1440&dlrmask=2&dlrurl=http://anotherserver.com/cgi-bin/dlr_process.cgi?to=004917878262267&test=hm&msg_id=4

I only seem to get the first paramater "to=004917878262267" back. All the 
examples I've seen with "type?%d" and so on don't seem to work. Am I 
barking up the wrong tree?

I will submit corrections to the docs as a result of my experience. As a 
starter it's "grab" and not "grap" and "built in" not "build in"

Cheers
