# raptor_cli module

# This module represents a Command Line Interpreter (CLI) for Raptor.

# The interface with Raptor is the GetArgs() function, which is called

# by a raptor.Raptor object.

Targets:

BITMAP         Create bitmap files

CLEAN          Remove built files and intermediates, but not exported files

CLEANEXPORT    Remove exported files

EXPORT         Copy exported files to destinations

FINAL          Allow extension makefiles to execute final commands

FREEZE         Freeze exported functions in a .DEF file

LIBRARY        Create import libraries from frozen .DEF files

LISTING        Create assembler listing files for source files

REALLYCLEAN    Same as CLEAN but also remove exported files

RESOURCE       Create resource files

ROMFILE        Create an IBY file to be included in a ROM

TARGET         Create main executables

WHAT           List all releaseable targets

Examples:

sbs -b my/group/bld.inf -c armv5        # build my component for target ARMV5

sbs -b my/group/bld.inf -c armv5.test   # build my tests for target ARMV5

sbs -c winscw CLEAN                     # clean emulator files

sbs REALLYCLEAN                         # delete everything""")
