[Lazarus] Compiling LCL units via commandline

[luciano de souza]

After reading your message, Mattias, I was persuaded the best solution
is to use Lazbuild. We will do a tool to write a lpi. I don't know if
I need to write also a lpk file. I suppose these files already exist.
Would All the work be to develop the tool to write lpis? Units wsould
be compiled in the correct order. Lazbuild can determine which order
is that or I need to fill up my lpi with instructions about the order
of compilation.
If all the knowledge needed to create this tool is read and write xml,
OK, the tool can be done. But if I need to know deeply the flags
passed to enqueue units in the correct order, also, the study needs to
be much more detailed.
