# SYNOPSIS
|
|
#
|
|
# Your package build config for executable programs

|
|
# DESCRIPTION
|
|
#
|
|
# We assume each .c file in this directory has a main() function, so
|
|
# that it becomes as easy as possible to write lots of tiny programs
|
|
#
|
|
# EXAMPLE
|
|
#
|
|
# make o//examples/package
