This is part 2 of a 2 part FAQ on using the Web to obtain geosciences
information on the Internet. This part deals with software and related
data which would be of interest to geosciences.

The chances are, if you use this faq, you will be transferring software
from one computer to another for the purpose of running the software.
Many of these programs will have been compressed and/or encoded by one or more
of several techniques for storage and transfer purposes. The method
of compression/encoding is indicated by the file extension - the (usually)
three characters after the "." in the file name. The most common compression/
encoding schemes are:

.zip - pkzip is a dos standard compressor/archiver. Also on unix.
.lzh - pc compression from lha archiver
.zoo - zoo.exe is a compressor/archiver
.Z   - unix compression program
.tar - unix tape archive.
.hqx - binhex, binary to 8 bit ascii encoded, predominantly for the Mac,
       but pc versions do exist. Needs binhex4
.sea - self extracting archive for the Macintosh
.sit - stuffit compression for the Macintosh, found in binhex4.
.gz  - gzip is a Unix compression, pc versions as well.
.exe - self extracting archive, can be created from pkzip and lha.
.uue - unix to unix 7 bit encoding, Dos versions exist

Most of these are available from popular ftp sites such as Sumex-aim,
oak.oakland etc. For a listing of common file formats, and links to relevant
software, connect to the Common File Formats page (see below).

A word of warning for Mac users, Mac binary files are stored differently
on a Unix machine than on a Mac (and Dos, VMS etc). Downloading a Mac
binary file (.bin, .sit etc) to a unix box which has not been encoded will
result in an unusable file. It is something to do with Unix zero filling
some of the unused bits in the Mac binary word.
