This is an older version of GNU sed which appears to work
better than the latest version. (sed 4.1.4 crashes a lot)

The binaries are compiled with clib2 and one version
with -unix (used Unix path-names instead of Amiga path-names).

From http://www.gnu.org/software/sed/sed.html :

"Sed (streams editor) isn't really a true text editor or text processor.
Instead, it is used to filter text, i.e., it takes text input and performs some
operation (or set of operations) on it and outputs the modified text. Sed is
typically used for extracting part of a file using pattern matching or
substituting multiple occurrences of a string within a file."
