+Install Program
+===============
+
+    Source: NuttX
+    Author: Uros Platise
+    Date: 7. May 2011
+
+This application installs XIP application by placing it directly into
+the program memory (flash) area into free area and creates a start-up
+script into selected directory (i.e. /usr/bin/progname).
+
+Usage:
+    install [--stack RequiredStackSpace] [--priority Priority] 
+            source-file destination-directory
+    
+If stackspace is not given default stack space of 4096 Bytes is used.
+If priority is not given system default is used.
+
+Additional options:
+
+    --remove destination-file   i.e. install --remove /usr/bin/myapp
+    --force                     to replace existing installation
+    --start <page>              install app at or after <page>
+    --margin <pages>            leave some free space after the kernel
+                                Default is 16 pages so kernel may grow.
