### copy_file/2

`copy_file(From, To) -> term()`

### count/2

`count(X, Xs) -> term()`

`escape_uri(Cs) -> term()`

### filename/1

`filename(T) -> term()`

### find_doc_dirs/0

`find_doc_dirs() -> term()`

### find_file/3

`find_file(Ps, Pkg, Name) -> term()`

### find_sources/2

`find_sources(Path, Opts) -> term()`

### find_sources/3
