\`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]
  --frameworks=DIR        build frameworks and install in DIR
  --gsmake=PATH           path to gnustep-make tree
  --configmake=PATH       path to the config file being created
  --with-gnustep          install in GNUstep tree
  --enable-debug          turn on debugging and compile time warnings
  --enable-strip          turn on stripping of debug symbols
  --with-ssl=SSL          specify ssl library (none, libssl, gnutls, auto) [auto]

Warning: you are configuring for a non standard FHS style prefix.
         prefix: $ARG_PREFIX

Some code in SOPE only looks in /usr and /usr/local for resources and is
therefore incompatible with arbitary install pathes.

If you want to have the flexibility of installation in arbitary pathes just
configure GNUstep-make and source the GNUstep.sh script prior executing tools
to ensure a proper environment.
All SOPE based code is completely relocatable when being used in a GNUstep
environment.
