Each error report is sent to the developer who presumably caused the warning. This is the person who last checked in the file that failed to compile. Additionally, the person responsible for the package will also receive the report.
The definition of the persons responsible for a package is stored in the text file projects.txt. The syntax self explanatory and can be demonstrated by means of a simple example:
vlsicap: sabelka, harlander wafer: binder xcircuit: grasser
This definition makes the persons sabelka and harlander responsible for the package vlsicap, the person binder responsible for the package wafer, and the person grasser responsible for the package xcircuit.
