// 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
