    ported by Matt Wu <matt at ext2fsd.com>
    http://github.com/matt-wu/e2fsprogs


Builing e2fsprogs for Windows under Cygwin:

1,  start cygwin console: (cygwin.bat)
    make sure you have cygwin gcc & make installed
2,  run make or make.sh (sh -x ./make.sh)


Run e2fsprogs utils:

1,  Administrator priviledge is required to access partitions or volumes.
2,  Block device name could be /dev/sdX or drive letter, Windows device
    *) /dev/sda4:                       the 4th partition of harddisk 0
    *) \Device\Harddisk0\Partition4:    Windows partition device: 4th of 1st disk
    *) X:                               Windows drive letter with ':'
    *) \Device\HarddiskVolume6:         Windows volume device

e2fsprogs README:

    This is the new version (1.42.13) of the second extended file
system management programs.

	From time to time, I release new versions of e2fsprogs, to fix
bugs and to make the utilities more robust.  You can always find
information about the latest version at the the e2fsprogs web page,
which is:

	http://e2fsprogs.sourceforge.net

	The INSTALL file has instructions on building and installing
e2fsprogs.  Provisions for building Red Hat RPMs and Debian dpkg files
are supplied as well.

	In case of bugs in these programs, please contact Ted Ts'o at
tytso@mit.edu or tytso@alum.mit.edu.  See the e2fsck man page for
suggestions of what sort of information to include when submitting bug
reports for these programs.
