+# actually adds, at the end, the list of packages for which the intercept script
+# is valid. Also, if one wants to pass any variables to the intercept script from
+# the postinstall itself, they will be added immediately after the shebang line.
+#
+# Usage: postinst_intercept <intercept_script_name> <package_name> <mlprefix=...> <var1=...> ... <varN=...>
+#  * intercept_script_name - the name of the intercept script we want to change;
+#  * package_name - add the package_name to list of packages the intercept script
+#                   is used for;
+#  * mlprefix=... - this one is needed in order to have separate hooks for multilib.
+#  * var1=... - var1 will have the value we provide in the intercept script. This
+#               is useful when we want to pass on variables like ${libdir} to
+#               the intercept script;
