+Catima Caluclator
+================
+Catima Caluclator is a command line application and interface to the catime library.
+
+Usage
+-----
+The application is executed from the command line:
+
+```
+    catima_calculator config_file";
+```
+
+example
+```
+    catima_calculator c.json
+```
+
+Config File Format
+------------------
+The file must be a valid JSON formatted file.  
+
+The json file should contain the following keys: "projectile", "material", "energy"
+
+#### projectile
+The __projectile__ keywords are:
+  * array - 2 number array, 1st is mass number, 2nd is charge of the projectile
+
+examples:
+```
+    "projectile":[11.997,6],
+```
+
+#### material
+The __material__ keyword is array of object for multi layer material,
+or single object defining the material.
+The material object must contain __Z__ keyword defining proton number 
+of the projectile or the compound material id. 
+Optional material object keywords are:
+  * __Z__ - proton number or compunds id, mandatory
+  * __A__ - mass number of the material, if 0 or undefined elemental atomic weight is used
+  * __density__ - density in g/cm3, if 0 or undefined the tabulated density will be used.
+  * __thickness__ - material or layer thickness in g/cm2
+
+#### energy
+The __energy__ keyword can be 
+1.a number specifying the kinetic energy:
+```
+    "energy":"500.0"
+```
+
+2. array of numbers for multiple energies:
+```
+    "energy":[100,200,500,1000]
+```
+
+3. Object specifying minimum energy, maximum energy and energy step, to calculate multiple energies:
+```
+    "energy":{
+        "min": 100,
+        "max": 1000,
+        "step": 10
+    }
+```
+instead of "step" key the "num" can be specified for integer number of steps between min and max energy.
+
+#### config
+The calculation configuration can be change using __config__ keyword. If 
+not specified default will be used. The config keyword is expected to be one of the strings
+  * "atimav1.3" - for Atima v1.3 setting
+  * "atimav1.4" - for Atima v1.4 setting
+```
+"config":"atimav1.4"
+```
