Appendix: Tips & Tricks

Due to the fact that PySPG calls the Python's eval() function, it will understand that if you say
```
+D 1 (2+6)/2 3/3 
```
You are meaning that you want D to vary from 1 to 4 with step of 1 !!!!
Due to the fact that the math module is imported, you can also say
```
+k log(5) log(5**5) log(sqrt(pi)) 
```

IMPORTANT LIMITATION
Due to the simple syntax of the file, it is also fragile in the sense that if you say

+k log(5) log(5** 5) log(sqrt(pi))

(note the extra space in 5** 5) it will fail to recognize the syntax I find more easy to avoid putting innecesary spaces that add a step of complexity considering list separators in the actual way I find the syntax of "param.dat" files, simple, easy to find errors
