Implement a daemon that expects to be invoked by a new-style init like upstart
or systemd as:
/usr/sbin/softetherd [vpnbridge|vpnclient|vpnserver]
Alternatively, if the command line argument is empty, then use the
`SOFTETHER_MODE` environment variable instead.
Sharing object code between vpnbridge, vpnclient, vpnserver, and vpncmd
reduces the binary size of SoftEther by 85% and its administrative memory
footprint by 50%.
Add autoconf and automake capabilities to SoftEther so that it can be built
like this:
# autoreconf --force --install
# ./configure
# make install DESTDIR=/tmp/softether
All standard configure parameters are supported, plus:
# ./configure --enable-debug
Autotools support makes porting, cross compiling, and optimization much easier.
These GNU autoconf-archive components are used for dependency checking:
* ax_check_openssl.m4
* ax_check_zlib.m4
* ax_lib_readline.m4
* ax_pthread.m4
* ax_with_curses.m4
