Welcome to the Public Ada Library (PAL).
Last Update: February 6, 1994
The Public Ada Library (PAL) is a library of Ada software, courseware,
and documentation on the Internet-based host computer named
wuarchive.wustl.edu (WUARCHIVE). The PAL is located in the directories
languages/ada and languages/vhdl if you access WUARCHIVE by FTP, archie,
gopher, or FTPMAIL, or in the directories /archive/languages/ada and
/archive/languages/vhdl if you access WUARCHIVE by NFS. The PAL reached
the Initial Operational Capability milestone in its evolution on June
21, 1993.
The purposes of the PAL are:
. to help make Ada-oriented software, courseware, and documentation
that has been released for public distribution (as shareware,
freeware, GNU Copyleft, etc) readily available to the public
. to support Ada educators by providing a convenient mechanism
for them to exchange material and ideas
. to support the Ada user community in general by providing a
resource in support of their activities
The PAL, which is located in the directory trees languages/ada and
languages/vhdl on WUARCHIVE, is actually five collections of material in
one:
1. the languages/ada/ajpo tree is a mirror of the public area of
the ajpo.sei.cmu.edu host computer; this collection is maintained
by the Ada Information Clearinghouse (AdaIC) under the direction of
the Ada Joint Program Office; as a mirror, whenever the AdaIC updates
its files on ajpo.sei.cmu.edu, the languages/ada/ajpo tree of the
PAL is automatically updated within 24 hours; documentation on the
languages/ada/ajpo tree is found scattered throughout the tree itself
and in the PAL Catalog
2. the languages/ada/sei tree is a mirror of the public area of the
ftp.sei.cmu.edu host computer; this collection is maintained by
the Software Engineering Institute (SEI); as a mirror, whenever the
SEI updates its files on ftp.sei.cmu.edu, the languages/ada/sei tree
of the PAL is automatically updated within 24 hours; documentation
on the languages/ada/sei tree is found scattered throughout the tree
itself and in the PAL Catalog
3. the languages/ada/asr tree is the principal copy of the Ada Software
Repository (ASR) on wsmr-simtel20.army.mil; the ASR is no longer
actively maintained; documentation on the languages/ada/asr tree is
found in the languages/ada/asr/mindex directory as the Master Index
document (files are named *.ch, containing chapters of the document)
and in the PAL Catalog
4. the languages/vhdl tree is a mirror of the VHDL Repository at the
University of Cincinnati, host uceng.uc.edu; this collection is
maintained by Dr. Harold Carter of the Department of Electrical
and Computer Engineering at the University of Cincinnati; as a
mirror, whenever the VHDL Repository is updated, the languages/vhdl
tree of the PAL is automatically updated within 24 hours; documentation
on the languages/vhdl tree is found scattered throughout the tree itself
and in the PAL Catalog
5. the rest of the languages/ada tree is the part of the PAL maintained
by the manager of the PAL; documentation is found in the directory
languages/ada/userdocs/catalog, which contains the PAL Catalog,
PAL LOTUS-123 and dBase IV compatible database files, and other
forms of catalog information on the PAL
Many organizations have developed cooperative relationships with the
PAL, contributing time, effort, user support services, and artifacts to
the PAL and its users either directly or indirectly. These
organizations include:
AdaNET
the Ada Joint Program Office
the Ada Information Clearinghouse
the Army Reuse Center
the Army's Communications Electronics Command (CECOM) Software
Engineering Directorate (SED)
the Asset Source for Software Engineering Technology
the Central Archive for Reusable Defense Software
Conservatoire National des Arts et Metiers (CNAM) in Paris, France
the DoD's Defense Information Systems Agency
the Software Engineering Institute
the Software Reuse Repository at the University of Maine
the VHDL Repository at the University of Cincinnati
Walnut Creek CDROM
The PAL can be accessed by a wide variety of mechanisms. These
mechanisms include, but are not limited to, the following:
. FTP to WUARCHIVE itself (up to 250 simultaneous FTP users)
. NFS mounts on WUARCHIVE
. Gopher email servers
. FTPMAIL email servers
. CDROM distributions
. AdaNET distributions and customer support (AdaNET is free to users)
To get started, look at the file 0FAQ in the directory
languages/ada
This is a frequently-asked questions list. If you are reading this from
the top level of the Walnut Creek Ada CDROM, you may execute the batch
file GO.BAT to run the interactive PAL Card Catalog. Finally, also in
languages/ada is the file 0MANIFEST, which gives a top-level view of the
contents of the PAL.
