## Getting started

Beginners should of course read Section 2, the beginner's guide. While doing this, you need only retain the topics with which you are concerned at first view. If anything seems to be lacking, then read the other topics.

After a few trials (say a few days of normal usage or a few drawings), most users will efficiently benefit from reading carefully Section 3. With some more practice, they will soon reach normal proficiency in GREG standard usage and be able to tackle the most funny things.

Section 4, the ``advanced'' user's guide, is important for those who want to get the best of GREG with colours, images, etc... It is also important for the application programmer who may use these features to provide a top layer for integrated applications.

Section 5,6,7 contains descriptions of all GREG commands on a command by command basis. This is a copy of the internal help. Please keep in mind that because of GREG evolution it may not be completely up to date.

At this stage, model builders (as opposed to observers) will most likely want to go further by using the `GREGLIB` and thus reading Section 8. This may be done sooner, but it is not recommended to use the `GREGLIB` before the basic concepts of GREG have been mastered.

The documentation on the SIC monitor is now provided separately in the manual SIC documentation, and at least the first chapter of this manual should be read by the beginners. The monitor offers many flexible capabilities such as procedures, symbols, vector mathematics, and so on.

The other sections concern only programmers of special purpose tasks, or system builders, and their lecture will be almost necessarily complemented by reading the SIC manual also. Note however that if you have some specific graphic problem, it is most likely solved somewhere in the GREG package, so that the answer may well be under these sections.

Know what you want ? Then go ahead, and good luck.
