=head1 SYNOPSIS

  Usage: configure [options]

  Options:

    -h, --help                    Show this help message and exit
    -v, --verbose                 Print verbose output

  Installation directories:

    --prefix=PREFIX               install architecture-independent files in PREFIX
                                  [/usr/local]

    --exec-prefix=EPREFIX         install architecture-dependent files in EPREFIX
                                  [PREFIX]

  By default, `make install' will install all the files in
  `/usr/local/bin', `/usr/local/lib' etc.  You can specify
  an installation prefix other than `/usr/local/' using `--prefix',
  for instance `--prefix=$HOME'.

  For better control, use the options below.

  Fine tuning of the installation directories:
    --bindir=DIR                 user executables [EPREFIX/bin]
    --sysconfdir=DIR             read-only single-machine data [PREFIX/etc]
    --localstatedir=DIR          modifiable single-machine data [PREFIX/var]
    --libdir=DIR                 object code libraries [EPREFIX/lib]
    --datadir=DIR                read-only architecture-independent data [PREFIX/share]
    --mandir=DIR                 man documentation [DATADIR/man]

  Optional Settings:

    --with-htmlurl=<local-url>   sets URL for public html [/thruk]

    --with-tempdir               sets the temp folder [PREFIX/tmp]
    --with-initdir               sets the folder for rc scripts
    --with-httpd-conf            sets path to Apache conf.d directory
    --with-logrotatedir          sets path to logrotates.d directory
    --with-logdir                sets path to log files [PREFIX/var/log/thruk]
    --with-thruk-libs            sets path to thruk libs directory [PREFIX/lib/thruk/perl5]
    --with-thruk-user            sets user name to run thruk [thruk]
    --with-thruk-group           sets group name to run thruk [thruk]
    --with-checkresultdir        sets path to Naemon/Nagios/Icinga/Shinken checkresult directory [PREFIX/var/cache/naemon/checkresults]
    --without-compress           skip compression of css and javascript files which requires yui-compressor
    --without-thruk-libs         skip building the required perl modules. Make sure you add dependencies accordingly
