Compiler fails with ' bad source file' error message if a panini file is not explicitly included in the set of files to compile.
For example, suppose you import org.paninij.io.PrintStream in some other file, say Foo.java, but do not include PrintStream.java in the build path, then when you run panc on Foo.java, compiler fails with
bad source file: src/panini/org/paninij/io/PrintStream.java
file does not contain class org.paninij.io.PrintStream
Attached archive has an example of the bug.
