# Indentation
|
|
# -----------
|
|
# Coq's syntax is based heavily on keywords and program structure,
|
|
# not based on explicit, unique delimiters, like braces in C-family.
|
|
# So it is difficult to properly indent using only regex...
|
|
# Hence here only a simple mechanism of copying indent is done.
