+  Usage: perl distillsrc.pl [-f file] [-m file] [-c file] -r src_root
+    -s source_path [-p src_prefix] -l platform [-n] [-d] [-h help];
+	
+  Options in detail:
+    -file|f file : components.txt file to read (may be more than one)
+    -mrp|m file : additional .mrp file to read (may be more than one)
+    -config|c file : a configuration file to use containing .mrp files to use
+    -r src_root : The root from which all src statements are based
+    -s source_path : The path under src_root to the source tree to be processed
+    -p src_prefix : An optional prefix which can be stripped from all src
+      statements
+    -l platform : The platform (beech etc), needed in order to locate the
+      correct product directory
+    -n : don't check the case of files in the config file and in .mrps against
+      the file system
+    -d : dummy mode
+      
+  Note that the src_prefix in combination with the src_root can be used to
+  displace the source tree, if it isn't in it's final location.
