PSGRN and PSCMP (packaged as fomosto backend)

Code to calculate synthetic stress/strain/tilt/gravitational fields on a layered viscoelastic halfspace.

PSGRN and PSCMP have been written by Rongjiang Wang.

Packaging has been done by Hannes Vasyura-Bathke.

Compile and install PSGRN and PSCMP

autoreconf -i   # only if 'configure' script is missing
./configure
make
sudo make install

To run PSGRN/PSCMP with more receivers/source points

Choose larger values in src/psgrn/psgglob.h, e.g.:
```
parameter(lmax=1000)
parameter(nrmax=4001)
```

Choose larger values in src/pscmp/pscglob.h, e.g.:

parameter(NZSMAX=5000,NRMAX=10000)
parameter(NPSMAX=40000)
parameter(NRECMAX=40000)

Recompile:
```
make clean
make
sudo make install
```
