| One common way to use dumper is to plug it into cygwin's Just-In-Time
| debugging facility by adding
| error_start=x:\path\to\dumper.exe
| to the CYGWIN environment variable. Please note that x:\path\to\dumper.exe
| is Windows-style and not cygwin path. If error_start is set this way, then
| dumper will be started whenever some program encounters a fatal error.
