Takin' it on the road, a sample program compile

Going to the putls repo:

Compiling dump.pas:

Notes:

1. Notice that this is a single line compile, "pc dump". That's all that is needed.
2. pc just needs to be on the path. It picks up the basic instructions from pc.ins in its bin directory.
3. dump.pas uses strings, services and parse libraries, which are satisfied from the ./lib directory.
4. dump.pas also uses dcnlib.pas, a direct console reading module. Notice that it finds it and compiles it from the same directory.

There are a bunch of basic utilities in this repo. I'll be going through them. There are some good program examples in Pascaline here.

Lesson

The lesson is, if your header files between the stripped header and the real header don't match, get ready for some strange errors.

pc compiles itself!
