+   This program creates a list of the source files (such as C headers) used to build the project
+for Eclipse CDT plugin. It only needs to be run for the new projects, the existing ones already
+have .cproject file distributed in each subproject repository (in 'eclipse_project_setup' sub-
+directory of the root sub-project directory). This sub-directory content is copyied to the sub-
+project root by setup.py when it is first run. You may delete .project file (while Eclipse is closed)
+and re-run setup.py (in elphel393 directory) restore default project settings if they get corrupted.
+
+   The program does not rely on exact duplicating of the environment used by bitbake, instead it
+"spies" on the bitbake by noticing which files it accesses during build (using file modification and
+access timestamps) and creates list of exclusions. As the access time is recorded only after the first
+access after modification, the program first unpacks/touches the sources.
+
+The extra_source directory is the specified in the command line directory (in addition to hard-coded
+'src') with sub-tree of the source files (headers) to be filtered.
+ 
+Here is the full sequence (target is the project name extracted from .cproject):
+1. bitbake target-c cleansstate
+2. bitbake target-c unpack -f
+3. bitbake target-c configure -f
+4. Scan all files under extra_source directory, find last modification stamp
+5. bitbake target-c compile -f
+6. bitbake target-c install -f # in the case of Linux kernel in triggers compilation of the kernel
+   modules
+7. Scan source files, create list of the used files and then list of excluded files (Eclipse CDT allows
+to specify directory and exclusion filter)
+8. Add (or replace) the record in .cproject file that specifies source directory and the filter
+
+You need to run indexing  (right-click on the project in the Navigator panel -> Index -> rebuild
+when the workspace is opened with the modified .cproject file.
+
+Do not run this program when Eclipse IDE is opened that includes the current project!
+
+The program should be launched from the project root directory, e.g. for applications:
+    ./scripts/used_files.py sysroots
+
+Program can either overwrite the current .cproject configuration file or create a new modified version
+if specified in teh command line argument. In that case program runs in debug mode and generates lists
+of files in the project root directory:
+    all_sources.lst - all scanned source file with last access timestamps
+    including.lst - list of the files (relative to specified extra_source directory) used by bitbake
+    excluding.lst - list of the unused files (they will appear crossed in the Project Navigator) 
+  
+USAGE:
+   %s extra_source [path-to-modified-cproject]
+   
+   First (mandatory) argument of this program (extra_source) is the relative path additional source/header
+   files. For Linux kernel development it is 'linux', for php extension - 'php, for applications - 'sysroots'
+   (symlink to header files) 
+   
+   Second (optional) argument (path-to-modified-cproject) is the relative to project root file to write
+   modified .cproject content. If specified it forces program to run in debug mode and generate 3 file lists.
