+ 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.
