------
ABOUT:
------
This is a straight rip from the e2fsprogs pkg.
These files are used to support other misc progs ripped out of e2fsprogs
and included in busybox.
-------
UPDATE:
-------
Simply copy the 'e2p' dir from e2fsprogs/lib/ and then delete the extra
files we don't need (Makefile.in, e2p.pc.in, etc...). Update the e2p.h
file to look for "../ext2_fs.h" instead of <ext2fs/ext2_fs.h>. Finally,
remove the _LARGEFILE* define's from the few source files that use it
since we'll be appending it ourselves to CFLAGS when we compile.
------
STAMP:
------
Last ripped from the e2fsprogs-1.37 release.
