# PARAM.SFO with its title, and pack that and a stripped copy of the ELF
# (no icon, pictures or sound) into the EBOOT.PBP. The unstripped ELF stays
# where it is, for psp-addr2line. Run as make/psp.mk's packing step.

# Usage: packEboot.sh PROGRAM.elf TITLE EBOOT.PBP

# Requires $PSPDEV (exported by make from the installer's
# toolchains/config.mk; toolchains/env.sh for a shell).
