General syntax:
---------------

- Statements can be written in multiple lines by ending the line with a backslash (\).
  Line breaks within strings are possible, but all whitespaces (space, tabulator, and
  the line break) before and after the backslash will be replaced by a single space.
  Example:
  Message "This is a test", \
          "Title"

- You can use expressions as parameter by setting them in braces.
  Example:
  Message {"1+1="&(1+1)},{"Title: "&%title%}

- Strings can contain these tokens: ^CR^ (carriage return), ^LF^ (line feed), and
  ^TAB^ (tabulator).

- Instead of "Set variable, value", you can use %variable% = value.
  The percent sings in this case are necessary to allow backward compatibilty with
  scripts using the old Command=Params syntax.

- Instead of "If expression", you can use "If { ... }" (resembles the {...} syntax
  for parameters) or "If ( ... )" (like in C, Java, ...).

Internet features
-----------------
The commands ReadIni, ReadFile, and ForEach with iniSections and iniKeys allow
URLs instead of filenames.
Example:
ReadIni http://www.foo.bar/versions.ini,Mort,MortRunner

There's also the new "Download" command.
More about these commands below.

New control structures
----------------------

ForEach variabe {,variable} in type parameters
   {commands}
EndForEach

There are multiple usages:

- ForEach variable in values value {, value}

  Assings each of the given values to the variable in each iteration. The values are
  common parameters, i.e. they can contain variables (%variable%) or expressions
  ({expression}).

- ForEach variable in split string, seperator, trim?

  Similar to the Split command (see below), but the variable will get each part in
  every iteration.

- ForEach variable in charsOf string

  Assigns each character of the string to the variable.

- ForEach variable in iniSections filename

  Assigns the section names of the given INI file to the variable.

- ForEach key, value in iniKeys filename, section

  Assigns the entries of the given section in the INI file to the variables given
  for "key" and "value".

- ForEach variable in files expression
  ForEach variable in directories expression

  Assings the found files resp. directories to the variable.
  The expression must contain jokers in the last level, e.g. "\Program Files\Mort*"
  or "\Program Files\Test\*.exe" (similar to XCopy or Move).

Switch value
Case value{,value}
   {commands}
EndSwitch

Just like Choose, but with a fixed value (or variable or expression) instead of
a dialog.


New commands:
-------------

Registry:

- RegDeleteKey root, path, delete values?, delete subkeys (recursive)?

  Deletes the registry key.
  "Delete values?" is also used for subkeys if "delete subkeys?" is 1. I.e.,
  RegDeleteKey HKCU,"\Software\Dings",0,1 would remove only empty subkeys (because
  subkeys with entries can't be deleted).
  If the key can't be removed, a message is shown if the ErrorLevel's on "warn" or
  lower.
  The path mustn't be empty to avoid accidental removing of an entiry registry
  section (e.g. if there's a typo in a variable). Still, this command has to be
  handled with care, esp. when using varialbes or expressions for the path!

Dialogs:

- Input variable, numbers only?, description [, title]

  Shows a dialog with an input field. The value entered will be assinged to the
  variable (or an empty string if "Cancel" is pressed).
  If "numbers only?" is 1, only numbers can be entered.

- SleepMessage seconds, message [, title]

  Shows a wait message with a countdown.

Files:

- IniRead filename, section, key, variable

  Reads a value for an INI file to the variable (empty string if it doesn't
  exist).

- ReadFile filename, variable

  Reads the entire contents of the file into the variable. The file size is
  limited to 128kB or the available memory (whichever is less).
  You can parse the file e.g. with ForEach line in split %contents%,"^LF^",1
  See also the ForEach possibilities for INI files and ReadINI!

- WriteFile filename, contents

  Writes "contents" to the file. If the file exists, it'll be overwritten.

- Download URL, target

  Similar to Copy, but uses an URL (http://... or ftp://...) as source and
  shows a progress window, because this usually takes a bit longer...

- GetVersion filename, variable
  GetVersion filename, variable, variable, variable, variable

  Gets the version number in the resources, either as string ("a.b.c.d") or
  into single variables.
  This information isn't contained or accurate in all files. If contained,
  the version is always in four levels, usually major, minor, patch, and
  build version.

System:

- GetSystemPath path, variable

  Receives the localized directory name for certain locations. Possible
  values for "path" are:
  * ProgramsMenu - "Programs" in Start menu
  * StartMenu    - Start menu
  * Startup      - Startup (links are run after soft reset)
  * Documents    - "\My documents", requires WM2003 or higher
  * ProgramFiles - "\Program files", requires WM2003 or higher

- GetColorAt x, y, variable

  Gets the color of the point. At least on some devices, the title bar is
  ignored, i.e. it receives the color of the underlying today background.
  The color is 0xbbggrr as decimal value.

- GetRGB red, green, blue, variable

  Coverts the decimal values of red, green, and blue parts (0-255 each)
  into the the same format as used by GetColorAt.

- GetWindowText x, y, variable

  Receives the window text of the element that's located at the given
  point. In most dialogs you can get labels or contents of edit boxes
  that way. It doesn't work as intended for application drawn elements
  (like in most games) or e.g. list boxes. In this cases, it'll usually
  return nothing (empty string) or the application's title.
