92 help
93 This adds a -jX option to certain packages that are known to behave well
94 for parallel build. By default, the package make processes use the main
95 jobserver, in which case this option only takes effect when you add -jX
96 to the make command.

106 This passes the main make process jobserver fds to package builds,
107 enabling full parallelization across different packages.
108
109 Note that disabling this may overcommit CPU resources depending on the
110 -j level of the main make process, the number of package submake jobs
111 selected below and the number of actual CPUs present.
112 Example: If the main make is passed a -j4 and the submake -j
113 is also set to 4, we may end up with 16 parallel make processes
114 in the worst case.

134 WARNING: This may break build or kill your cat, as it builds packages
135 with multiple jobs that are probably not tested in a parallel build
136 environment.
137
138 Only say Y if you don't mind fixing broken packages. Before reporting
139 build bugs, set this to N and re-run the build.
