FAQ

What is Lhogho?
Lhogho is one of the hundreds implementations of the Logo language (see The Logo Tree). However, unline most other Logos, Lhogho is a compiler.

Why is it called Lhogho?
We wanted a name which sounds like Logo, but is written in a way which noone else has ever seen before. We did search "Lhogho" in the major search machines (back in 2005) and we got 0 hits.

How to pronounce "Lhogho"?
We don't know. We asked several English native speakers, but they ricocheted back to us the same question. So far we pronounce it the same way as "Logo", but with a slight double-wink.

Who does develop Lhogho?
Lhogho is developed by an independent team. The team leader is assoc. prof. Pavel Boytchev, PhD. As an open source project we exect that other professional would join us.

My Logo programs do not work with Lhogho?
There is a bouquet of possible reasons for this: your Logo and Lhogho are really incompatible; or you need a feature which is not available in Lhogho (yet); or there is a bug in Lhogho; or ...

I want to help. What can I do?
Please drop a message in the Developrs forum.
