History

For completeness, here are some of the major upgrades in this software, with some of the key authors. Please note that the list is not exhaustive: it is intended to illustrate the diversity of contributors and complex history of the software. Dates are quite approximate too, since the list is reconstructed from non-ECC astronomer memory.

GILDAS is essentially coded in Fortran-77 (98 % of the code), with just a few C routines for system interface (including with the X-Window system).
