# Helper file defining standard targets for Shark applications.  It should

# be included from the application makefiles in this way (preserving much

# of the old behavior):

#

# # Example of Shark application makefile.

# S?=<source tree>

# B?=<build tree, if different from $(S)>

#

# SUBDIRS:= <list of subdirectories>

# APPS:= <list of applications>

#

# include $(S)/mk/App.mk

#

# # For each <application>:

# <application>:

#	make -f $(S)/Makefile APP=<application> \

#		OTHEROBJS="<list of objects>" \

#		OTHERINCL="<list of extra include dirs>" \

#		SHARKOPT="<list of options>"

#

# # End of Shark application makefile example.
