- This help file identifies formats and utilities used, and describes each
to assist users of this information service. In no case does such identification
imply recommendation or endorsement by the National Institute of Standards and
Technology.
- ASCII - Where neither a PS or PDF file was available or where size allowed, there is an ASCII
version available. Note that some versions may contain conversion errors particularly where
tables and charts were present in the original.
- Postscript (PS) - Documents annotated with
 require a postscript viewer (such as Ghostview), or must be downloaded to your system for printing on a postscript printer. You can obtain free public-domain postscript viewers from http://www.cs.wisc.edu/~ghost/index.html
- Portable Document Format (PDF) - Documents annotated with
 require Adobe Acrobat Reader Software for viewing. You can download free Adobe software from http://www.adobe.com/supportservice/custsupport/download.html
- Perl (.pl) - Several tools were written using the Perl language syntax. In most cases, these tools are shown in ASCII for viewing. These tools must be saved to your local disk with a .pl extension in order to be executed by Perl. Reference http://www.perl.com for more information on installing and using the Perl language.
- C (.c) - Several tools were written using the C programming language syntax. In most cases, these tools are shown in ASCII for viewing. These tools must be saved to your local disk with a .c extension in order to be executed. Reference each tool for comments regarding execution arguments.
- We have tarred and zipped directory structure/files so that users may download
all at once. Note that some browser-OS combinations appear to be dropping the extension
from downloaded files. The file content transfers, but the file doesn't end with the
appropriate extension. If this happens, rename the files to have the same extension as
shown on the web page you're downloading from. After downloading the tarred and zipped
file, variations of the following utilities may be used to "unzip" and "untar" the directory
structure/files onto your system.
- Tar utility - Archives and extracts files and/or directories from a
single file called a tar file (.tar). For more information on this utility, reference http://kb.indiana.edu/data/acsy.html
- ZIP utility - Reduces the size of named files, whenever possible. Each file
is replaced with .gz or .Z while keeping the same ownership modes, access and
modification times. For more information on this utility, reference
All About ZIP Files.
