-"""pump v0.2.0 - Pretty Useful for Meta Programming.
-
-A tool for preprocessor meta programming. Useful for generating
-repetitive boilerplate code. Especially useful for writing C++
-classes, functions, macros, and templates that need to work with
-various number of arguments.
-
-USAGE:
- pump.py SOURCE_FILE
-
-EXAMPLES:
- pump.py foo.cc.pump
- Converts foo.cc.pump to foo.cc.
-
-GRAMMAR:
- CODE ::= ATOMIC_CODE*
- ATOMIC_CODE ::= $var ID = EXPRESSION
- | $var ID = [[ CODE ]]
- | $range ID EXPRESSION..EXPRESSION
- | $for ID SEPARATOR [[ CODE ]]
- | $($)
- | $ID
- | $(EXPRESSION)
- | $if EXPRESSION [[ CODE ]] ELSE_BRANCH
- | [[ CODE ]]
- | RAW_CODE
- SEPARATOR ::= RAW_CODE | EMPTY
- ELSE_BRANCH ::= $else [[ CODE ]]
- | $elif EXPRESSION [[ CODE ]] ELSE_BRANCH
- | EMPTY
- EXPRESSION has Python syntax.
