   depends on #76 and possibly significant extra work if the APU uses callbacks.

   Is the dependency on #76 the reason I get near-empty F2jFITPACK.{java,class} when I made a brief attempt at it - as opposed to missing something other than core/pom.xml that would need to be changed?

   if by "near empty" you mean "completely empty". We need to compile the fortran code for the JVM before we can even think about adding it to netlib-java.

   For my purposes I got interpolation matching SciPy output, by adapting FITPACK code translated by f2j.

   Up to you whether to keep this issue open for more general interest in FITPACK.
