There is a great deal of locally added software on newt. To find it, have a look in the directory tree starting at /usr/local. To get help on an item of local software, use man just as you would for the standard UNIX commands, e.g., to get help on tex, type
man tex
The following subsections detail some of the available packages.
There is an arbitrary precision mathematics package in /usr/local/src/apml. This allows exact calculations for additions, subtractions, and multiplications, and a user-specifiable accuracy for divisions. The package is written in C, and Michael Ashley has written some FORTRAN routines to access it, including routines for handling complex numbers (see the fortran subdirectory).
The program f2c will take a FORTRAN source file and generate a C equivalent, which you then have to link against a couple of emulating libraries. f2c may be useful in the case that the FORTRAN compiler generates buggy code, or if you wish to port a FORTRAN program to a machine that doesn't have FORTRAN.
The procedure for making a binary is
f2c prog.f
which creates prog.c, and then
cc -I/usr/local/include prog.c -lF77 -lI77 -lm -lc
to generate the binary.
IRAF, the Image Reduction and Analysis Facility, written by Kitt Peak Observatory in the United States, is available on the workstation. To use it for the first time, type the following commands
cd mkdir iraf cd iraf mkiraf xterm& cl ! from within the xtermTo use it subsequently, all you need to do (after starting up an xterm) is
cd ~/iraf clcl stands for ``command language'', and is the IRAF user interface. Once in cl you can type help for information, or logout to get back to the UNIX shell.
The following programs are not part of the usual UNIX command set, and have been obtained mostly from public domain sources.
New items of local software will be added on an ongoing basis. Check the /usr/local directory tree for details. Use this software at your own risk, no guarantees are given that any given package will work, is installed correctly, or will remain on the system. If your work requires one of these programs, then you are strongly advised to make a copy of it on magtape.
