I'd suggest to use make_ini for the byte-compiling.

     * can do this in the postinst script with:
     
         cd <dir where the file is installed, e.g. Jed_Site_Library>
         jed --batch -f 'byte_compile_file("<myfile.sl>", 0)'
       
       (this is the fast way) or 
         
         jed --batch -l make_ini.sl
         
       (this will also incorporate the tm-documentation)  
     
     * must remove <myfile.slc> when it is removed.

     cd <Jed_Site_Library>
     jed --batch -l make_ini.sl

     in its postinst script to update the slc files and the documentation
     of extra packages.

     (I can add dfa-syntax generation support to make_ini if this is
      required)
     

Packages that add a .sl file to Jed_Site_Library must make sure, that it
is "byte-compilable".

Removing jed-common will not remove files of other packages (be they *.sl
or *.slc). (But re-installing or updating jed-common will overwrite an
existing *.slc with a new byte-compiled version.)

Isn't this far easier than a directory of scripts?
