3.3 Creating the checksum file

Just type make makesum. The ports make rules will automatically generate the file distinfo.

If a file fetched has its checksum changed regularly and you are certain the source is trusted (i.e. it comes from manufacturer CDs or documentation generated daily), you should specify these files in the IGNOREFILES variable. Then the checksum is not calculated for that file when you run make makesum, but set to IGNORE.
