# Apply patches:
# Make the default data directory /etc/file like it has always been:
zcat $CWD/file.etc.file.diff.gz | patch -p1 --verbose || exit 1
# This is needed after the patch above:
autoreconf || exit 1

# Since we're going to include the compiled magic database now (otherwise
# there seem to be libmagic related crashes), this patch probably doesn't
# need to be applied.
#
## Don't spew warnings about using the flat text files
#zcat $CWD/file.quiet.diff.gz | patch -p1 -E --verbose || exit 1

# Keep the output format for ELF binaries the same as it was in earlier
# versions of file to avoid breaking existing scripts:
zcat $CWD/file.short.diff.gz | patch -p1 -E --verbose || exit 1

# Add zisofs and crda regulatory bin detection
zcat $CWD/file.zisofs.magic.gz >> magic/Magdir/compress
zcat $CWD/file.crdaregbin.magic.gz >> magic/Magdir/crdaregbin
