+# Use this script as a wrapper when running executables linked to shared
+# libraries on systems that use the $LD_LIBRARY_PATH variable and don't embed
+# the soname's path within the linked executable (such as IRIX), e.g,
+#
+# shlib knight
+#
+# Setting LD_LIBRARY_PATH, overrides/supplements the loader's normal search
+# path, and works on most systems. The drawback is that then the environment
+# variable has to be set to run the programs within this directory tree.
+#
+# For Linux (and other systems using the GNU loader), we can use the rpath
+# directive, which embeds the pathname of the library within the executable.
+# Using the Linux loader's rpath directive introduces a constraint, since
+# it's embedded into the binary, and means that the binary cannot be moved
+# around (though it'll work if the $exec_prefix convention that puts the bin
+# and lib directories under the same parent is followed).
+#
+# Using the actual soname (e.g., ../lib/libncurses.so) alone, is a more
+# flexible solution; you can link without having to set the environment
+# variable, and on some systems (IRIX) you can even run the resulting binaries
+# without setting LD_LIBRARY_PATH.
+#
+# Using a conventional link, with -L and -l options on Linux results in a
+# statically linked executable, which we don't want at all.
+#
+# Special cases:
+#
+# BeOS R4.5 uses $LIBRARY_PATH rather than $LD_LIBRARY_PATH.
+# Cygwin uses $PATH
+# Mac OS X uses $DYLD_LIBRARY_PATH
+#
+# Other cases not handled by this script:
+#
+# AIX uses $LIBPATH
+# IRIX64 may use $LD_LIBRARY64_PATH or $LD_LIBRARYN32_PATH
+# Solaris may use $LD_LIBRARY_PATH_64
+#
