What to use for finding as many syntax errors as possible.

[Antoon Pardon]

I would like a tool that tries to find as many syntax errors as possible 
in a python file. I know there is the risk of false positives when a 
tool tries to recover from a syntax error and proceeds but I would 
prefer that over the current python strategy of quiting after the first 
syntax error. I just want a tool for syntax errors. No style 
enforcements. Any recommandations? -- Antoon Pardon
