DESCRIPTION

  Build script used to create a local install of this package. It can also
  be used to preform a staged installation by specifying a destdir, in which
  case the files are copied instead of linked. 

SYNOPSIS

  $script_name [--prefix=path] [--destdir=path] [--conf] [--package]

OPTIONS

  --prefix=path   absolute path to installation directory for conf files
                  and link to the executable
                  default: \$VAP_HOME

  --destdir=path  absolute path prepended to prefix used
                  to perform a staged installation

  --conf          only install the conf files

  --package       only install the python package

  --uninstall     uninstall locally installed package

  -h, --help      display this help message
