use strict;

my $log = Chilkat2::Log->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, "\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
