- # 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;
