11 | # Master machine independent configuration file. | |
12 | # | |
13 | # Specific configuration files are created based on this and | |
14 | # the machine specific master file using the doconf script. | |
15 | # | |
16 | # Any changes to the master configuration files will affect all | |
17 | # other configuration files based upon it. | |

20 | # | |
21 | # To build a configuration, execute "doconf <configuration>." | |
22 | # Configurations are specified in the "Configurations:" section | |
23 | # of the MASTER and MASTER.* files as follows: | |
24 | # | |
25 | # <configuration> = [ <attribute0> <attribute1> ... <attributeN> ] | |
26 | # | |
27 | # Lines in the MASTER and MASTER.* files are selected based on | |
28 | # the attribute selector list, found in a comment at the end of | |
29 | # the line. This is a list of attributes separated by commas. | |
30 | # The "!" operator selects the line if none of the attributes are | |
31 | # specified. | |
32 | # | |
33 | # For example: | |
34 | # | |
35 | # <foo,bar> selects a line if "foo" or "bar" are specified. | |
36 | # <!foo,bar> selects a line if neither "foo" nor "bar" is | |
37 | # specified. | |
38 | # | |
39 | # Lines with no attributes specified are selected for all | |
40 | # configurations. | |
