8                      Statement of Purpose and Disclaimer  O The anonymous area on hmivax.humgen.upenn.edu is maintained as a public service K to the scientific community.  It is intended to serve as a source of public D domain software and information of use to members of this community,N particularly in the areas of genetics and molecular biology.  While reasonableL efforts are made to maintain this service, no warranty is made by any personL associated with this facility, the University of Pennsylvania, or the HowardG Hughes Medical Institute, that the information available is accurate or G current, or that the software available will function in any particular J fashion.  In addition, we cannot accept any responsibility for any damagesK arising directly or indirectly from use of information or software obtained  here.   L All files available in the anonymous area are, to the best or our knowledge,K freeware  or shareware.  In keeping with the goals of this facility and the O regulations governing use if the Internet, no commercial software may be placed ? here, nor may this service be used for any commercial purposes.     0                               Retrieval of Files  M Files may be retrieved from the public directories over the Internet by means F of anonymous FTP.  Since many implementations of FTP are available forH different systems, the specific capabilities of your system and modes ofN transfer available to you may vary.  In general, documents and source code mayP be transferred as ASCII files, while executable images require binary transfer. J If you have the appropriate compiler on your system, it is usually best toK transfer source code and recompile it at your site, as problems often arise . during attempts to transfer executable images.  O While we make reasonable efforts to insure that software and information posted O here are freely available and perform reasonable functions, we cannot guarantee N the performance of any software or the accuracy of any information, nor can weL accept responsibility for the consequences of use of anything retrieved fromO this facility.  As always, when you download *anything* test it in a restricted J environment to insure that it performs its intended function safely before: using it where it could cause harm to your system or data.  K Many files are archived using a compression algorithm to minimize the space J consumed by the information.  These files must be uncompressed in order toN generate a useful version.  The type of compression used varies from system toJ system, and is often signified by the extension of the archived file.  ForJ example, the .UUE extension is used to designate files compressed with theH UUENCODE program; these must be uncompressed using UUDECODE before use. M Compression and uncompression utilities are available in the public domain or O as shareware from many sources; some of the common programs are archived here.  = In general, archived files may be transferred as ASCII files.   ? Many groups of related files are accompanied by an uncompressed O documentation file which explains what the compressed files contain, and how to K get and use them.  Look for files with the .TXT or .DOC extension, or names  containing README or HELP.    3                            Leaving Files for Others   N If you wish to upload a file for use by others, please feel free to do so.  IfN possible, try to use an archiving utility which is available here, or supply aD copy of the utility to us.  In addition, please include some kind of- documentation describing what the file(s) do.   M Please upload all files to the [.NEWFILES] directory.  They will be archived, H if necessary, and moved to the appropriate directory as soon as we get aM chance.  Please do not upload any software that cannot be distributed freely.   I We reserve the right to remove software which is not being used, which we P consider inappropriate to the purpose of this facility, or for which there is no space.    *                                    General  G Please exercise common sense and courtesy when using this facility.  In M particular, please try to limit use to low demand hours (usually evenings and N weekends), and do not upload large numbers of files which are of little use to the community at large.   M If you encounter any problems with use of this facility or with any files you B retrieved from here, please send e-mail describing the problem andD circumstances to bailey@hmivax.humgen.upenn.edu as soon as possible.  N Thank you for your cooperation.  We hope you find the resources here useful in
 your work.
