A note for Debian maintainers: The upstream source of HEALPix for Java is distributed in a monolithic tarball that also includes the C, C++, Fortran, IDL, and Python language variants. The debian/watch file for this package strips out the unrelated source directories from the upstream tarball. Due to the extreme simplicity of this package, I opted to use javahelper instead of the upstream-provided build.xml Ant file.
