Changes since 0.2
-----------------

o manifest improvements
  o variables
    o added more ways to initialize variables: values and files
    o added more variables (replacing hard-coded elements and attributes):
      o name
      o version
      o description
      o license
      o readme
    o renamed all variables to lower case
  o configurable installer classes:
    the file installer.xml lists the classes that make up the installer gui;
    by adding user-defined classes, it is possible to execute custom code on
    the target machine.
  CAUTION: these changes are *not* compatible with packlet 0.2.
  Please refer to examples/hello/manifest.xml and examples/advanced/manifest.xml,
  these files demonstrate the new syntax for manifest files.
  
o improved file format
  o bzip2 compression (instead of gzip compression used in packlet 0.2)
  o improved handling for large files:
    to unpack a file, it is no longer necessary to the complete file into memory
  
o bug fixes
  o text file handling
    o if the source file didn't end with a linefeet, a linefeet was added to the target file
  o builder
    o exit code != 0 for syntax errors
  o gui
    o directory step
      o browse dialog now allows to select new directory

o source code
  o cleanup of the IO code

o build system
  o switched to mork 0.5, ant 1.5, junit 3.8
  o some cleanup in build.xml

  
Changes since 0.1
-----------------

o added a CRC32 checksum:
  before running the installer, the complete packlet file is checksummed

o added variables: variables are used
  o to configure the installer
  o to check the environment on the target machine
  o for substitution in template files
  Please refer to the manifest.dtd file for more information.
  
o removed checks, variables provided the same functionality (and more)
  o migration: change
        <check function="javaVersion" arg="1.2.0">Java version</check>
    -->
        <var name="java" function="getJavaVersion" arg="1.2.0" public="Java version"/>
    and
        <check function="operatingSystem" arg="dummy">Operating system</check>
    -->
        <var name="os" function="getOperatingSystem" public="Operating system"/>
  
o improved text file handling
  o When adding text files to a packlet:
    o the line separator is converted from the source machine's line separator to the Unix
      line separator.
    o the character encoding is converted from the source machine's default character encoding
      to UTF-8
  o When extracting text files from a packlet:
    o the line separator is converted from Unix line separators to the separator specifed by the LF.
      LF defaults to the target machine's line separator.
    o the character encoding is converted from UTF 8 to the character encoding specified
      by the ENCODING variable. ENCODING defaults to the target machine's default character
      encoding.

o merge identical source files being installed in multiple locations

o build system
  o dump ant from the distribution
    + smaller download
    + fixes jdk 1.2 build problems
    - build packlet becomes more difficult
  o added javadoc target

o fixes
  o quoting problem in windows launch script templates
  o resource name problems on windows:
    o test for absolute file names was broken
    o resource name to file name translation was missing

o cleanup
  o split installer package into manifest and gui package
  o ClassLoader
    o simplified the class loader to reduced the file size
    o reduced memory consumption
    o ignore classes on the user's classpath
    o added test cases
