"""Reads stdin and extracts a list of all header dependencies to
|
|
a file. It requires exactly one argument.
|
|
|
|
The input is expected to take form of C preprocessor output, where
|
|
paths to originating input source files are indicated via the form
|
|
# LINENO "PATH"
|
|
|
|
The argument to the script is the target file to be overwritten.
|
|
It will contain the extracted dependencies (unquoted absolute paths).
|
|
|
|
Relative paths generated by the C preprocessor are resolved relative
|
|
to the current working directory (see Bug 652544)."""
