+This is probably the simplest PLASMA program you can write:
+```
+include "inc/cmdsys.plh"
+
+puts("Hello, world.\n")
+done
+```
+However, it is significant in that it demonstrates the basic layout of a PLASMA source file. Almost all PLASMA files will have `include "inc/cmdsys.plh"` at the beginning. All PLASMA files have to end with a `done` line. There could be more text afterwards, but it will be ignored by the compiler. Potentially a good place to put some documentation of the above code. And in the middle, we have a function call to put a string to the screen. The screen has an embedded carriage-return at the end, formatted like you would see in a C language style string, escaped with a `\` character.
