This code was created for a starpack based installer/updater project we have at Unitas Software. I may have updated versions available, drop me a line if you are curious/want to have it.

# Usage:
#
# Include kitsplit.tcl and a suitable pkgIndex.tcl in your starpack
#
# API Documentation:
#
# kitsplit /TclkitToWrite/ /ApplicationkitToWrite/
# Writes a tclkit.exe and application.kit file from the currently running
# starpack. Existing files will be overwritten.
#
# /TclkitToWrite/ full path for the tclkit.exe
#
# /ApplicationkitToWrite/ full path for the application.kit
# if the name ends with .vfs, an unwrapped version
# will be written instead.
#
# writeKitExe /TclkitToWrite/
# Writes a tclkit.exe running starpack.
# If the tclkit.exe already exists an error is raised.
#
# /TclkitToWrite/ full path for the tclkit.exe
#
# writeKitFile /ApplicationkitToWrite/ ?/wrapped/?
# Writes a application.kit from the running starpack.
# If the application.kit already exists an error is raised.
#
# /ApplicationkitToWrite/ full path for the application.kit
# /wrapped/ Boolean value, 0 = write .vfs directory, 1=(default) write .kit file
#
# unwrap /VFSDirToWrite/
# Writes a application.vfs/ from the running starpack.
# If the application.vfs/ already exists an error is raised.
#
# /VFSDirToWrite/ full path for the application.vfs/
#
# runningAsStarpack
# Returns 1 if the currently running application is a starpack, 0 otherwise.
# Query $::starkit::mode to figure out other states such as unwrapped,
# starkit, ...
#
# Example:
# package require kitsplit
# namespace import kitsplit::*
#
# if { [runningAsStarpack] } {
# kitsplit c:/path/to/desired/tclkit.exe c:/path/to/desired/application.kit
