## Script environment variables

| Value               | Comment                         |
| -----               | -------                         |
| MESON_SOURCE_ROOT   | Absolute path to the source dir |
| MESON_BUILD_ROOT    | Absolute path to the build dir  |
| MESONINTROSPECT     | Command to run to run the introspection command, may be of the form `python /path/to/meson introspect`, user is responsible for splitting the path if necessary. |
| MESON_SUBDIR        | Current subdirectory, only set for `run_command` |

## CPU families

These are returned by the `cpu_family` method of `build_machine`,
`host_machine` and `target_machine`. For cross compilation they are
set in the cross file.

| Value               | Comment                         |
| -----               | -------                         |
| x86                 | 32 bit x86 processor  |
| x86_64              | 64 bit x86 processor  |
| ia64                | Itanium processor     |
| arm                 | 32 bit ARM processor  |

| mips64              | 64 bit MIPS processor |
| ppc                 | 32 bit PPC processors |
| ppc64               | 64 bit PPC processors |
| e2k                 | MCST Elbrus processor |
| parisc              | HP PA-RISC processor  |
| sparc64             | SPARC v9 processor    |

Any cpu family not listed in the above list is not guaranteed to
remain stable in future releases.

## Operating system names

These are provided by the `.system()` method call.
