-# Usage:
-#   install-reloc library_path_var library_path_value prefix \
-#                 compile_command srcdir config_h_dir exeext \
-#                 install_command... destprog
+# Usage 1:
+#   install-reloc -- library_path_var library_path_value prefix destdir \
+#                    compile_command srcdir builddir config_h_dir exeext \
+#                    strip_command \
+#                    install_command... destprog
 # where
 #   - library_path_var is the platform dependent runtime library path variable
 #   - library_path_value is a colon separated list of directories that contain
 #     the libraries at installation time (use this instead of -rpath)
 #   - prefix is the base directory at installation time
+#   - destdir is a string that is prepended to all file names at installation
+#     time; it is already prepended to destprog but not to library_path_value
+#     and prefix
 #   - compile_command is a C compiler compilation and linking command
 #   - srcdir is the directory where to find relocwrapper.c and its dependencies
 #   - builddir is the directory where to find built dependencies (namely,
 #     alloca.h and stdbool.h)
 #   - config_h_dir is the directory where to find config.h
 #   - exeext is platform dependent suffix of executables
-#   - install-command is the install command line, excluding the final destprog
+#   - strip_command is the command for stripping executables, or : if no
+#     stripping is desired
+#   - install_command is the install command line, excluding the final destprog
 #   - destprog is the destination program name
+# Usage 2:
+#   env RELOC_LIBRARY_PATH_VAR=library_path_var \
+#       RELOC_LIBRARY_PATH_VALUE=library_path_value \
+#       RELOC_PREFIX=prefix \

+#       RELOC_STRIP_PROG=strip_command \
+#       RELOC_INSTALL_PROG=install_command... \
+#   install-reloc prog1 ... destprog
+#   where destprog is either the destination program name (when only one program
+#   is specified) or the destination directory for all programs.
 # install-reloc renames destprog to destprog.bin and installs a relocating
 # wrapper in the place of destprog.
