  ./configure [--someoption=somevalue ...]

For help on options or configuring run
  ./configure --help

Build and install binaries with the usual
  make
  make check
  make install

Or just build the Debian packages without configuring
  dpkg-buildpackage -rfakeroot

When building from Git, you need these Debian packages:
  autoconf, automake, libtool, gcc, bison, any tcl,
  xsltproc, docbook, docbook-xml, docbook-xsl,
  libxslt1-dev, libssl-dev, libreadline5-dev, libwrap0-dev,
  libpcap0.8-dev

Also perhaps: libgnutls-dev libicu-dev

And if you want to make a Debian package: dpkg-dev fakeroot debhelper
(Then run "dpkg-buildpackage -rfakeroot" in this directory.)
