.\"O .SH DESCRIPTION
.SH ÀâÌÀ
.\"O \*(Sd is a stream editor.
.\"O A stream editor is used to perform basic text
.\"O transformations on an input stream
.\"O (a file or input from a pipeline).
.\"O While in some ways similar to an editor which
.\"O permits scripted edits (such as \fIed\fP),
.\"O \*(sd works by making only one pass over the
.\"O input(s), and is consequently more efficient.
.\"O But it is \*(sd's ability to filter text in a pipeline
.\"O which particularly distinguishes it from other types of
.\"O editors.
