20# Usage:
21#   install-reloc library_path_var library_path_value prefix compile_command srcdir config_h_dir exeext install_command... destprog
22# where
23#   - library_path_var is the platform dependent runtime library path variable
24#   - library_path_value is a colon separated list of directories that contain
25#     the libraries at installation time (use this instead of -rpath)
26#   - prefix is the base directory at installation time
27#   - compile_command is a C compiler compilation and linking command
28#   - srcdir is the directory where to find relocwrapper.c and its dependencies
29#   - builddir is the directory where to find built dependencies (namely,
30#     alloca.h and stdbool.h)
31#   - config_h_dir is the directory where to find config.h
32#   - exeext is platform dependent suffix of executables
33#   - install-command is the install command line, excluding the final destprog
34#   - destprog is the destination program name
35# install-reloc renames destprog to destprog.bin and installs a relocating
36# wrapper in the place of destprog.
