# genScript.sh
#
# a shell script to generate linker scripts.
#
# TODO:
# 1. convenience labels like etext, edata, end, and wrs_kernel_*_{start,end}
#    are primarily used by ROM kernels and can most likely be omitted from RAM
#    kernels. But they're harmless and it makes script sharing easier.
# 2. "classic" convenience labels (etext/edata/end) should be phased out in
#    favor of the newer ones. Further, DAT has requested that we make the new
#    names conform to wrsInitialCapitals style.
# 3. Due to the template generation strategy employed here, the final output
#    may look a little awkwardly formatted and certainly is not as clean and
#    simple as the early versions of the Diab scripts. Suggestions welcome.
#    I actually think this might not be such a bad application for (gasp!) Tcl,
#    so a future Tcl rewrite (which also helps windows users) is possible.
# 4. Currently GNU aligns everything to 16. This is probably overkill on many
#    chips, and especially once everyone is ELF, the internal section alignment
#    should take care of things -- except for convenience labels which need to
#    guarantee 4 byte alignment for use with copyLongs and fillLongs.
# 5. General convergence...
