is to use shell scripts to generate everything. * generic.em replaces ldtemplate. * Other *.em files replace various *.c files. A *.em file is a shell script that generates the corresponding ld__*.c file that implements an emulation. This is usually a straight 'cat' of a here-document, possibly with substitutions. * Script files (*.sc) are places by *.sc-sh scripts. Again, these are simple shell scripts that 'cat' here-documents, usually with some substitutions. The output a *.sc-sh is a script file.
