I just added this to the Parted documentation.  Does this help?  Please
tell me if some parts don't make sense.

Thanks,

SITUATION
 
Suppose your disk layout looks like this:
 
        (parted) print
        Disk geometry for /dev/hda: 0.000-1000.000 megabytes
        Disk label type: msdos
        Minor    Start       End     Type      Filesystem  Flags
        1          0.063    500.000  primary   ext2
        2        500.000    625.000  primary   linux-swap
 
There is 375 Mb of free space at the end of the disk (after partition
2).
Partition 1 has an ext2 file system, which is the root device. 
Partition 2
is a swap device.
 
Suppose you wanted to use the free space at the end of the disk for the
file]
system on partition 1.

EXAMPLE PROCEDURE
 
(1) The following steps will modify both the root file system on
partition 1,
and the swap device on partition 2.  Therefore, you shouldn't be using
either
partitions.  You should probably use a Parted boot disk (see section
1.5).
>From the boot disk, run Parted:

        # parted /dev/hda
 
(2) Remove partition 2 (the swap partition).  Normally, you wouldn't
want to
delete a partition with data on it.  However, a swap partition doesn't
contain
data when it isn't "swapped on" (mounted), so you can remove it, and
create a
replacement swap partition later.
 
        (parted) rm 2
 
(3) Create the new swap partition at the end of the disk:
 
        (parted) mkpartfs primary linux-swap 875 999.9
        (parted) print
        Disk geometry for /dev/hda: 0.000-1000.000 megabytes
        Disk label type: msdos
        Minor    Start       End     Type      Filesystem  Flags
        1          0.063    500.000  primary   ext2
        2        875.000   1000.000  primary   linux-swap
 
(4) Grow partition 1, into the adjacent free space:
 
        (parted) resize 1 0.063 0.874.9
 
All done!
 
        (parted) print
        Disk geometry for /dev/hda: 0.000-1000.000 megabytes
        Disk label type: msdos
        Minor    Start       End     Type      Filesystem  Flags
        1          0.063    874.999  primary   ext2
        2        875.000   1000.000  primary  
linux-swap
