This package was debianized by Matt Ryan , then maintained by Sean E. Perry and is maintained by Florian Hinzmann now. I got the actual upstream version from http://www.xfmail.org At Debian systems you will find the GPL and LGPL licenses in /usr/share/common-licenses/. Refer to that folder instead to file COPYING mentioned below. Copyright: Copyright (c) 1998-2001 The Archimedes Team (http://archimedes.sourceforge.net) Copyright (c) 1995-1998 Gennady B.

Additional Permissions granted: This program is designed to use the XForms library, so we consider permission to link to that non-GPL-compatible library is implicit. However, in case this is not considered so, we explicitly state: 'As a special exception, the Archimedes Project, with the permission of all earlier copyright holders, formally gives permission to link this program with the XForms library, and distribute the resulting executable without the source code for XForms in the source distribution'. Permission to link to the Compface library, which this program is designed to optionally use and for which source code is provided (but which may have a GPL-incompatible license), is also formally given on the same terms as for linking to the XForms library. (Other included code not licensed under the GPL/LGPL is licensed under terms believed to be compatible with distribution under the terms of the GPL.) This software is provided 'as is' without any expressed or implied warranty of any kind. Under no circumstances is the author responsible for the proper functioning of this software, nor do the authors assume any responsibility for damages incurred by its use. See the Copyright file included in the distribution ------------------------------------------------------------------------------ The following files were not created by the XFMail authors, but were borrowed from other sources and added (in some cases after some modification) to the XFMail distribution: src/mail/md5.* - Implementation of "RSA Data Security, Inc. MD5 Message-Digest Algorithm". Copyright (C) 1991-2, RSA Data Security, Inc. src/compface/* - the compface library, used for compressing and uncompressing X-Faces. This is linked only if -DFACE is defined. src/regex/* - the GNU regular expression library. Added only for those platforms that lack a built-in regex or have unsupported version of it (like SunOS). This is not needed under Linux or FreeBSD. Linked only if --with-regex used with configure. src/editor/* - Text editor library. Copyright (c) 1996, Mark Van Kempen. src/ui/RdBitF.c - From X-Consortium X11 library. Needed on those platforms that lack XReadBitmapFileData. Not needed under Linux or FreeBSD with X11R6 (XFree86-3.x). src/mail/util.c - do_move() and fastcopy() are heavily based on BSD source. ------------------------------------------------------------------------------
