- ------
- 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.
