I've got a quick question regarding deisel and what it can do, versus LISP routines...

I've just been hired at a new company and they use AutoCAD 2008 LT, which, as I understand, cannot accept LISP routines. This is bad news for me, as I've build up (and gotten very used to) a comfortable set of LISPs, and I don't know how I feel about not being able to use them.
 
I've read somewhere that deisel can actually 'cover' some of the command customizations that LISPs perform in full versions of AutoCAD. Is this true? If so, why are LISPs locked out in LT and not deisel? And if this kind of command customization is possible, can someone please point me in the right direction for learning how to write/edit these functions?
 
Also, what are the differences between LISPs and deisel? Meaning, is deisel limited in any way that LISPs are not? Sorry if this is an ignorant sounding question, I honestly know nothing about this and have several web pages bookmarked already for some evening reading tonight. I just thought I'd ask here and get an answer from a real person.
 
Thanks for any help...

AutoCAD LT is a limited version of AutoCAD. One of these limitations is the programming API - no programming languages can be used inside AutoCAD LT.
 
DIESEL is a very limited macro language and you can perform just a small number of automation tasks in it. Most of the LISP routines cannot be rewritten in DIESEL. You can find help files for DIESEL in the Customization Guide (maybe in full AutoCAD's CG).
