use chilkat();

$log = chilkat::CkLog->new();

# Initialize the log object with an initial context tag:
$log->Clear("myLog");

# Add some information..
$log->LogInfo("Hello, I'm here...");

# Open a sub-context
$log->EnterContext("abc");

# New information is now logged within the "abc" context.
$log->LogInfo("This is inside the abc context");
$log->LogError("File not found.");

# Perhaps open a new context...
$log->EnterContext("fileInfo");
$log->LogData("filename","something.txt");
$log->LogData("path","/somedir/xyz");
$log->LeaveContext();

# Close the "abc" context.
$log->LeaveContext();

# Examine the content of the log:
print $log->lastErrorText() . "\r\n";

# 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
#   --abc
# --myLog
