upc and upx are programs which create and decompose empeg upgrade
files.
An empeg upgrade file can be used to reprogram (almost) every part
of the empeg player, including the boot loader, the linux kernel and
complete filesystems.
upc takes a list of resources as input and concatenates the data
for each resource to make a complete upgrade.
upx does the reverse, splitting an upgrade in to its constituent parts.
The two programs are complementary:
upx foo | upc > bar
is a complicated way of copying foo to bar.
