## Install/uninstall 'linked scripts' or win32 wrappers
## to use it, add prerequisite uninstall-links to uninstall-hook and
##  one ore more of install-{lua,perl,shell}-scripts to install-data-hook
##
## requires conditionals WIN32 and WIN32_WRAP
## requires $(scriptsdir): e.g., texmf/scripts/chktex
## appends to $(nodist_bin_SCRIPTS) and $(EXTRA_DIST)
##
## install-lua-scripts requires $(lua_scripts), e.g., musixflx
## install-perl-scripts requires $(perl_scripts), e.g., deweb
## install-shell-scripts requires $(shell_scripts), e.g. htlatex
##
## shell_scripts are somewhat special because win32 needs
## additional .bat scripts or similar
