			== Description ==
			This script will check a string (or directory path) for spaces and returns the number of spaces found in the string.

			Updated 12th January 2005

			== Usage ==
			The CheckForSpaces function should be called in the Leave function of the Directory page. Below are the two ways to implement this (through Classic UI and Modern UI). Both implement a function called "DirectoryLeave" as the Directory pages' Leave function.

			=== MUI ===
			Use this if you are using Modern UI (<i>!include MUI.nsh</i>).
			<highlight-nsis>
			!define MUI_PAGE_CUSTOMFUNCTION_LEAVE "DirectoryLeave"
			!insertmacro MUI_PAGE_DIRECTORY
			</highlight-nsis>

			=== Non-MUI ===
			Use this if you aren't using Modern UI.
			<highlight-nsis>
			Page Directory "" "" "DirectoryLeave"
			</highlight-nsis>

			=== DirectoryLeave Function ===
			This gives an example of what your "DirectoryLeave" function should look like.
			<highlight-nsis>
			Function DirectoryLeave

			# Call the CheckForSpaces function.
			Push $INSTDIR # Input string (install path).
			Call CheckForSpaces
			Pop $R0 # The function returns the number of spaces found in the input string.

			# Check if any spaces exist in $INSTDIR.
			StrCmp $R0 0 NoSpaces

			# Plural if more than 1 space in $INSTDIR.
			StrCmp $R0 1 0 +3
			StrCpy $R1 ""
			Goto +2
			StrCpy $R1 "s"

			# Show message box then take the user back to the Directory page.
			MessageBox MB_OK\|MB_ICONEXCLAMATION "Error: The Installaton directory \
			has $R0 space$R1.$\nPlease remove the space$R1."
			Abort

			NoSpaces:

			FunctionEnd
			</highlight-nsis>

			== The Function ==
			<highlight-nsis>
			Function CheckForSpaces
			Exch $R0
