# make_wince_cab.py --- Given a directory, walk it and make an
#          installer based upon the contents of that directory
#
# Usage:
#   python make_wince_cab.py [-setupdll] [-s] [-faststart] [CABWIZ_PATH] SOURCE_DIR PROGRAM_NAME CAB_FINAL_NAME
#
# Walk through the relative directory SOURCE_DIR, parsing filenames
#   Checks for duplicate filenames and renames where needed
#   Then builds a WinMobile INF file based upon results
# 
# Each directory in SOURCE_DIR may have a file named
# 'install-exceptions', which lists files in SOURCE_DIR that
# need not be placed into an installation CAB file. The
# 'install-exceptions' file itself is always ignored.
# 
# Blank lines and '#' comments in the 'install-exceptions' file are
# ignored.
#
# ARGS:
#   -setupdll - Make a small additional CAB including Setup.dll.
#               This is to add Fennec to the system list of installed applications
#               available in Settings - System - Remove Programs.
#
#   -s - Don't pass /compress to cabwiz (generate CAB compatible with Windows CE)
#
#   -faststart - Add FastStart shortcut
#
#   CABWIZ_PATH - If specified, will use this cabwiz.exe executable.  Otherwise, will attempt
#                 to find one using $VSINSTALLDIR.
#
#   SOURCE_DIR - sub-directory which contains the target program 
#                NOTE: It is assumed that the application name is SOURCE_DIR.exe
#                EXAMPLE: source_dir=fennec, there should be a fennec/fennec.exe application
#
#   PROGRAM_NAME - Name of the program to place inside the INF file
#
#   CAB_FINAL_NAME - actual final name for the produced CAB file
#
# EXAMPLE OF COMMAND LINE:
#   python make_wince_cab.py /c/Program\ Files/Microsoft\ Visual\ Studio\ 9.0/SmartDevices/SDK/SDKTools/cabwiz.exe dist/fennec Fennec fennec-0.11.en-US.wince-arm.cab
#
# NOTE: In our example, "fennec" is the directory [source_name]
#                       "fennec.exe" is the application [$(source_name).exe], and
#                       "Fennec" is the shortcut name [program_name]
