Compilation and Installation:

In order to compile VTun you need several software packages.
Required packages: 
  - Good C compiler (gcc, egcs, etc)
  - Lexical Analyzer (flex, lex)
  - YACC (yacc, bison, byacc)
  - Universal TUN/TAP driver 	http://vtun.sourceforge.net/tun
  - OpenSSL encryption library 	http://www.openssl.org 

Optional packages:
  - Zlib compression library	http://www.gzip.org/zlib/
  - LZO compression library 	http://www.oberhumer.com/opensource/lzo/
  - SOCKS library:
	 Socks5 by NEC (recommended)	http://www.socks.nec.com 
	 Dante Socks4/5 	http://www.inet.no/dante 

To configure VTun run:
  aclocal
  autoconf
  ./configure 
Optional support:
  --disable-lzo  	compile without LZO compression support
  --disable-zlib  	compile without ZLIB compression support
  --disable-shaper  	compile without Traffic shaping support
  --enable-socks 	compile with SOCKS support

Configure automatically searches for all required library and header
files.  However you might need to specify location of the files which
could not be found in default location:
  SSL(Crypto) library:
  --with-ssl-lib=/path/to/library (libcrypto.a) 
  --with-ssl-headers=/path/to/headers (md5.h blowfish.h)

  LZO library:
  --with-lzo-lib=/path/to/library (liblzo.a) 
  --with-lzo-headers=/path/to/headers (lzo1x.h)

  SOCKS library:
  --with-socks-lib=/path/to/library (libsocks.a or libsocks5.a) 

To compile and install run:
  make install

Read manual page for 'vtunemd' and the config file example for
configuration and other suggestions.
