#
# This makefile provides the following phony targets:
#
#    all  install  debug  resources  rom  rom_link
#
#
# This fragment uses the following macros set by the master makefile.
#
#
# COMPONENT                 (the name of the component)
# TARGET              (opt) (the leafname of the application - otherwise ${COMPONENT})
# DBG_TARGET          (opt) (debug application leafname - otherwise ${TARGET}-D)
# ROM_TARGET          (opt) (partially linked module-wrapped leafname - otherwise ${TARGET}.aof)
# LNK_TARGET          (opt) (fixed-position module-wrapped leafname - otherwise ${TARGET}.linked)
# INSTAPP             (opt) (the application target directory - otherwise ${INSTDIR}/!${COMPONENT})
# INSTDIR             (opt) (the target directory - otherwise ${INSTALLDIR}/${TARGET})
# RESFSDIR            (opt) (actual directory to export non-application-dir resources to - otherwise ${RESDIR}/${COMPONENT})
# RESFSAPPDIR         (opt) (where to register application-dir resources to within ResourceFS, using RISC OS style directory separators - otherwise Apps.!${COMPONENT})
# DIRS                (opt) (stamp object for directory creation - otherwise _dirs)
# OBJS                (opt) (object files, no o. prefixes - otherwise ${TARGET})
# APP_OBJS            (opt) (release build object files, no prefixes - otherwise ${OBJS})
# DBG_OBJS            (opt) (debug build object files, no prefixes - otherwise ${OBJS})
# ROM_OBJS            (opt) (ROM module-wrap build objects - otherwise ${OBJS} plus modulewrap and ${RES_OBJ})
# LIBS                (opt) (extra libraries; ${CLIB} is always used)
# APP_LIBS            (opt) (extra release libraries - otherwise ${LIBS}; ${CLIB} is always used)
# DBG_LIBS            (opt) (extra debug libraries - otherwise ${LIBS}; ${CLIB} and ${DEBUGLIBS} always used)
# ROM_LIBS            (opt) (libraries to link for ROM module-wrap targets - otherwise ${LIBS}; ${ROMSTUBS} or ${ROMCSTUBS} is always used, depending on whether ${LIBS} contains ${RLIB} or not)
# WRAPPER             (opt) (module-wrap source file to use - defaults to $LIBDIR/RISC_OSLib/modulewrap.s)
# ROM_DEPEND          (opt) (any extra dependency to assert on ROM_TARGET)
# LINK_TYPE           (opt) (variant of linking command, eg C++ - defaults to C)
# INSTTYPE            (opt) (use "tool" or "app" to install executable vs application - defaults to "tool")
# INSTAPP_FILES       (opt) (list of files to be installed in application directory - use InstRes specification rules)
# INSTAPP_DEPENDS     (opt) (list of dependencies to be satisfied before doing application install - ${TARGET} assumed if in INSTAPP_FILES)
# INSTAPP_VERSION     (opt) (list of Messages/!Run/Desc files to insert app version from VersionNum - include in INSTAPP_FILES as well)
# RES_FILES           (opt) (list of files to be installed in ${RESFSDIR} when building a module-wrap ROM - use InstRes specification rules. Where these conflict with the files in INSTAPP_FILES, prefer a subdirectory named 'ROM')
# RESAPP_FILES        (opt) (list of files to be installed in ${RESFSAPPDIR} when building a module-wrap ROM - use InstRes specification rules. Where these conflict with the files in INSTAPP_FILES, prefer a subdirectory named 'ROM')
# CUSTOMLINK          (opt) (set to "custom" to override the link rule)
# CUSTOMINSTALLAPP    (opt) (set to "custom" to override the install rule for resource files)
# CUSTOMINSTALLTOOL   (opt) (set to "custom" to override the install rule for target binary)
# CUSTOMINSTALLDBGAPP (opt) (set to "custom" to override the install rule for debug resources)
# CUSTOMROM           (opt) (set to "custom" to override the rom module-wrap rules)
# SOURCES_TO_SYMLINK  (opt) (files which need be linked to by the link farm, in addition to contents of c and h directories)
#
#
# It relies on the following generic tool macros from the StdTools makefile
#
#
# C + CFLAGS       (C compiler; CDFLAGS also used in debug builds; -g implicit)
# CP + CPFLAGS     (copy, cp etc.)
# WIPE + WFLAGS    (recursive delete)
# RM               (non-recursive delete)
# AS + ASFLAGS     (assembler)
# LD + LDFLAGS     (linker; LDDFLAGS also used in debug builds; -d implicit)
# SQZ + SQZFLAGS   (binary compressor)
# MKDIR            (cdir/mkdir -p)
# ECHO
# TOUCH            (create/touch)
# INSERTVERSION    (awk script to substitute from VersionNum)
#
#
# It relies on the following from the StdRules makefile
#
#
# .c.o  .c++.o  .cpp.o  .s.o
#
#
# It relies on the following from the DbgRules makefile
#
#
# CDFLAGS  C++DFLAGS  ASDFLAGS  LDDFLAGS
