Well, yes, that's sufficient for "Hello, world", but not for something barely more complex, i.e a function with a unit test. In this case, I had to type: rdmd -unittest --main test.d Without the --main, I would get linker errors, and couldn't find the reason for these errors. Happily, someone here explained me that the effect of the --main flag was to insert a main() function just for this case. Now, I see there is a mention of this in http://dlang.org/rdmd.html But without rdmd, I would compile with dmd, which has no --main switch, and it would still fail to link, because of lack of main(). The code I posted wasn't my code, and I knew it had worked, so I assumed it was correct, I didn't figure out that adding a main() was necessary given there was a unit test. And anyway, explaining in the book how to link is a necessary step imho. This is why I made this page more visible in the Wiki: http://prowiki.org/wiki4d/wiki.cgi?D__Tutorial/CompilingLinkingD
