\`configure' configures a GNUstep-make based sourcetree for installation.

Usage: $0 [OPTION]...

Note: You do not need to configure this source tree, as another option
      just ensure that the GNUstep.sh of your GNUstep make installation
      is properly sourced prior running make.

Configuration:
  -h, --help              display this help and exit
  -q, --quiet, --silent   do not print \`checking...' messages
  -n, --no-create         do not create output files

Installation directories:
  --prefix=PREFIX	  install files in PREFIX [/usr/local]
  --gsmake=PATH           path to gnustep-make tree
  --configmake=PATH       path to the config file being created
  --enable-debug          turn on debugging and compile time warnings
  --enable-strip          turn on stripping of debug symbols
  --enable-thread-safety  turn on thread-safety

  --enable-ldap-config    enable LDAP based configuration of SOGo
