! 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.
