INSTALLATION

Requirements:
    - JRE 6 
    - Android SDK (to work with a device or an emulator) 

Unpack a zip archive to any folder. 

Use the OS-specific script to launch the logviewer:
    - logview.bat (Windows) 
    - logview (Linux) 
Both scripts expect the javaw/java to be on your PATH. 

OVERVIEW: FILTERS

The following filtering criteria are supported:
    - Tag(s) 
    - Message text 
    - PID(s) 
    - Log priority 

Filtered lines can be:
    - Showed (all other lines will be hidden) 
    - Hidden 
    - Highlighted 
    - Showed in a separate window

You may enter several tags or PIDs separated with commas, any of them will be filtered.
Message filter supports regular expressions.
If several criteria are specified, only records that match all of them will be filtered.

OVERVIEW: SEARCHING

    1. Ctrl+F - show search field
    2. Enter the pattern, then press Enter to start searching
    3. F3 - find next, Shift+F3 - find previous
    4. Esc - clear search results
You should wrap your pattern into "/.../" - slashes - to search using regular expressions, 
ex. "/^[Aa].*$/" - all lines that start with lower or upper 'a'. Regex-based searching is 
case-sensitive in opposite to a simple searching. Standard Java regular expression 
syntax is used.

OVERVIEW: OTHER

    - The bookmarks windows can be used for quick jumping between marked lines. Use context 
      menu to add a line to bookmarks.
    - You can copy log lines to the clipboard using Ctrl+C, Ctrl+Ins or the context menu
    - Double-click on tag, message or pid cell opens edit mode where you can select and copy 
      a substring of the cell's content
