[3a4cb53] | 25 | <para>One method that <command>file</command> uses for identifying a given |

| 27 | contents to data in <quote>magic files</quote>, which contain information |
---|
| 28 | about a number of standard file formats. When File is compiled, it will run |
---|

---|
| 30 | magic files in its source tree into a single <filename>magic.mgc</filename> |

---|
| 32 | <xref linkend="chapter-temp-system"/>, it will be cross-compiled, so it |
---|
| 33 | will not be able to run the <command>file</command> program that it just |

| 34 | built, which means that we need one that will run on the host system.</para> |
