  19 # Usage:
  20 #   install-reloc library_path_var library_path_value prefix destdir \
  21 #                 compile_command srcdir builddir config_h_dir exeext \
  22 #                 strip_command \
  23 #                 install_command... destprog
  24 # where
  25 #   - library_path_var is the platform dependent runtime library path variable
  26 #   - library_path_value is a colon separated list of directories that contain
  27 #     the libraries at installation time (use this instead of -rpath)
  28 #   - prefix is the base directory at installation time
  29 #   - destdir is a string that is prepended to all file names at installation
  30 #     time; it is already prepended to destprog but not to library_path_value
  31 #     and prefix
  32 #   - compile_command is a C compiler compilation and linking command
  33 #   - srcdir is the directory where to find relocwrapper.c and its dependencies
  34 #   - builddir is the directory where to find built dependencies (namely,
  35 #     alloca.h and stdbool.h)
  36 #   - config_h_dir is the directory where to find config.h
  37 #   - exeext is platform dependent suffix of executables
  38 #   - strip_command is the command for stripping executables, or : if no
  39 #     stripping is desired
  40 #   - install_command is the install command line, excluding the final destprog
  41 #   - destprog is the destination program name
  42 # install-reloc renames destprog to destprog.bin and installs a relocating
  43 # wrapper in the place of destprog.
