+define Package/sed/description
+sed (stream editor) is a non-interactive command-line text editor. sed is commonly 
+used to filter text, i.e., it takes text input, 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.
