 == DESCRIPTION
 
-*lsfd* is intended to be a drop-in replacement for *lsof*(8) on Linux systems. It uses Libsmartcols for output formatting.
+*lsfd* is intended to be a modern replacement for *lsof*(8) on Linux systems.
+Unlike *lsof*, *lsfd* is specialized to Linux kernel; it supports Linux
+specific features like namespaces with simpler code. However, it is not a
+drop-in replacement for *lsof*; they are different in the command line
+interface and output formats.
+
+*lsfd* uses Libsmartcols for output formatting. See the description of *--output*
+option for customizing.
