  • tar xjf from the root directory
  • Ricksep does not work. Appears to be some incompatibility in Motif
  • This is new so there are additional bugs

Probably most SEP researcher have contributed in some way to SEPlib. However, some researchers stand out:

  • Robert Clayton introduced the original parameter fetching and did much ground breaking work concerning Vplot.
  • Jon Claerbout introduced history files.
  • Dave Hale wrote the libvplot library.
  • Stew Levin got SEPlib pipes to work and ported Vplot to DEC Gigi terminals.
  • Joe Dellinger perfected Vplot, the graphics library.
  • Steve Cole added dithering of rasterplots to Vplot.
  • Dave Nichols reworked the SEPlib input and output handling and introduced GNUmakefiles for easy installation.
  • Martin Karrenbach had a first SEPlib extension to handle irregular data.
  • Biondo Biondi and Bob Clapp (with the help of current SEP students) truly extended SEPlib to handle irregular data.

The directory seplib-5.1 contains software known as “SEPLIB” and “VPLOT”.
