LogAnayzer is a text editor specifically designed to analyze log files faster and easier by allowing the user to create, store and apply rules.

It has three main components:

1. Log Viewer: Displays a section of the original log file. (Upper right)
2. Rule Set: Manages the rules available to analyze the log. (Left)
3. Index: Provides an ordered list of the rule matches found on the log. (Lower right)

Rules are the key element of this tool. When a rule is applied to a log file each
line of the log file will be tested against it. For each line that contains all the rule
patterns a new match is added to the index.

A rule has the following elements:

1. Name: Unique identifier for each rule.
2. Example: A line of text that matches the rule criteria.
3. Patterns: A list of strings that must be present on a log line for the rule to match.
4. Variables: A list of strings "trapped" between patterns on lines that match.
5. Format: How a match will be added to the index.

The index can be used to browse through the log file or exported to
document the signature of the defect.
