# Linking pushmail statically or dynamically with other modules is

# 
# In addition, as a special exception, the copyright holders of
# pushmail give you permission to combine pushmail with free software
# programs or libraries that are released under the GNU LGPL and with
# code included in the standard release of OpenSSL under the OpenSSL
# License or the Original SSLeay License (or modified versions of such
# code, with unchanged license). You may copy and distribute such a
# system following the terms of the GNU GPL for pushmail and the
# licenses of the other code concerned, provided that you include the
# source code of that other code when and as the GNU GPL requires
# distribution of source code.
# 
# Note that people who make modified versions of pushmail are not
# obligated to grant this special exception for their modified
# versions; it is their choice whether to do so. The GNU General
# Public License gives permission to release a modified version
# without this exception; this exception also makes it possible to
# release a modified version which carries forward this exception.

# The purpose of this file is to check that all dependencies are
# available under licenses that are compatible with the GPLv2 and
# later versions.  Notably, the Apache-2.0 license is not compatible
# with the GPLv2.  If we need to depend on a library available only
# under Apache-2.0, we'd need to bump the GPL minimum to 3.0.
# Additionally, if we added a dependency on a GPL library, we'd need
# to make sure pushmail was only licensed under a subset of the GPL
# versions that library is licensed under, and that, like us, the
# library offered an exception for linking with OpenSSL.
