A program for computing element abundances and stellar parameter from
spectra.  It was supplied by Corrado Boeche, 2014, who was directly
committing in our repository. The two src and src-2.0 directories
contains the source of the current version 1.4 and the new branch that
may lead to the version 2.0 (but hasn't seen activity in a while).

Corrado now and then provides new versions that typically break
the service or at least change expected results.  When a new version
is there, make sure you change the version variable in the Makefile
before running make install.  You'll also manually have to fix the links
in res/download.shtml manually (for now).

The program needs a fairly large spectral library, the location of
which is configured in res/spacecore.py (parFile).  Let's consistently
call these spectral-library-vX.Y.

When devloping, just do the equivalent of
sshfs alnilam:/data/gavo/inputs/sp_ace/data/spectral-library-v1.4 data/spectral-library-v1.4/

Then go to http://localhost:8080/sp_ace/q/c/form and choose
test_data/low-res-example.asc as file.

If the formats of the result files change, you'll need to
change res/resultgrammar.py as well as test_data/response_scaffold.dat
and test_data/space_model_scaffold.dat, which are used in regression
tests.  To obtain them, run python3 res/spacecore.py and copy
response_scaffold.dat and space_model_scaffold.dat from your home to
test_data.

To build the fortran binary, you'll need libopenblas-dev and liblapack-dev
