# |
|
# * 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. |
