progsreiserfs is a collection of tools for manipulating ReiserFS filesystems. There are tools to create, check, resize, tune and copy ReiserFS filesystems. . These tools differ from the standard Namesys ReiserFS tools in that they use libreiserfs to do their work. . Reiserfsprogs is the "official" implementation, created by namesys. Progsreiserfs is an alternate implementation. It does the same thing; which you use depends on your preference.
