//  Initialize the log object with an initial context tag:
loo_Log.Clear("myLog")

//  Add some information..
loo_Log.LogInfo("Hello, I'm here...")

//  Open a sub-context
loo_Log.EnterContext("abc")

//  New information is now logged within the "abc" context.
loo_Log.LogInfo("This is inside the abc context")
loo_Log.LogError("File not found.")

//  Perhaps open a new context...
loo_Log.EnterContext("fileInfo")
loo_Log.LogData("filename","something.txt")

loo_Log.LeaveContext()

//  Close the "abc" context.
loo_Log.LeaveContext()

//  Examine the content of the log:
Write-Debug loo_Log.LastErrorText

//  This is the output:

//  myLog:
//    Hello, I'm here...
//    abc:
//      This is inside the abc context
//      File not found.
//      fileInfo:
//        filename: something.txt
//        path: /somedir/xyz
//      --fileInfo
