# * All of the .pde files are concatenated, starting with the file named
|
|
# for the sketch and followed by the others in alphabetical order.
|
|
# * An insertion point is created in the concatenated file at
|
|
# the first statement that isn't a preprocessor directive or comment.
|
|
# * An include of "WProgram.h" is inserted at the insertion point.
|
|
# * The file following the insertion point is scanned for function definitions
|
|
# and prototypes for these functions are inserted at the insertion point.
|
|
#
|
|
# In addition, we add #line directives wherever the originating file changes
|
|
# to help backtrack from compiler messages and in the debugger.
