"""Class to extract system information from a MS-Windows Box:
|

|
|
Instructions for Using:
|
||
|
|
|
||
|
|
Instance the class WindowsSystemInformation
|
||
|
|
Then in the instance, access the following variables:
|
||
|
|
|
||
|
|
os
|
||
|
|
cpu
|
||
|
|
totalRAM
|
||
|
|
totalVM
|
||
|
|
availableVM
|
||
|
|
availableRAM
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
s = SystemInformation()
|
||
|
|
print s.os
|
||
|
|
|
||
|
|
s.refresh() # if you need to refresh the dynamic data (i.e. Memory stats, etc)
