 Helper script for checking DLLs
 
 .DESCRIPTION
-This script does three things:
-- displays build configuration
-- displays target CPU information
-- displays informtaion about Jit Optimization
+This script displays information about every dll located in a given path
 
-.PARAMETER StartPath
-Location of the folder where your DLLs live.
+You can get information about
+- FileVersion
+- ProductVersion
+- LegalCopyright
+- BuildConfiguration
+- TargetCPU
+- JitOptimized flag
+
+.PARAMETER DllFolder
+Location of the folder with dlls.
 
 .EXAMPLE
 Test-DLL "C:\dll" -CleanHost
-Clears console and then displays information about all DLLs located in "C:\\dll"
