convertCppComments()
|
Converts the comments in a file.
This function does three things:
- It converts multi-line C++ style comment blocks (that are aligned) to C style comment blocks (if MULTILINE_CPP_IS_BRIEF is set to NO).
- It replaces aliases with their definition (see ALIASES)
- It handles conditional sections (cond...endcond blocks)
