54 | <refsect1><title>Description</title> | |
55 | <para><command>apt-ftparchive</command> is the command line tool that generates the index | |
56 | files that APT uses to access a distribution source. The index files should | |
57 | be generated on the origin site based on the content of that site.</para> | |
58 | ||
59 | <para><command>apt-ftparchive</command> is a superset of the &dpkg-scanpackages; program, | |
60 | incorporating its entire functionality via the <literal>packages</literal> command. | |
61 | It also contains a contents file generator, <literal>contents</literal>, and an | |
62 | elaborate means to 'script' the generation process for a complete | |
63 | archive.</para> | |
64 | ||
65 | <para>Internally <command>apt-ftparchive</command> can make use of binary databases to | |
66 | cache the contents of a .deb file and it does not rely on any external | |
67 | programs aside from &gzip;. When doing a full generate it automatically | |
68 | performs file-change checks and builds the desired compressed output files.</para> | |

76 | The packages command generates a package file from a directory tree. It | |

78 | emitting a package record to stdout for each. This command is | |
79 | approximately equivalent to &dpkg-scanpackages;.</para> | |

101 | the list of files matched to packages. Directories are not written to | |
102 | the output. If multiple packages own the same file then each package is | |

127 | <varlistentry><term>generate</term> | |
128 | <listitem><para> | |
129 | The <literal>generate</literal> command is designed to be runnable from a cron script and | |
130 | builds indexes according to the given config file. The config language | |
131 | provides a flexible means of specifying which index files are built from | |
132 | which directories, as well as providing a simple means of maintaining the | |
133 | required settings.</para></listitem> | |

144 | <refsect1><title>The Generate Configuration</title> | |
145 | <para> | |
146 | The <literal>generate</literal> command uses a configuration file to describe the | |
147 | archives that are going to be generated. It follows the typical ISC | |
148 | configuration format as seen in ISC tools like bind 8 and dhcpd. | |
149 | &apt-conf; contains a description of the syntax. Note that the generate | |
150 | configuration is parsed in sectional manner, but &apt-conf; is parsed in a | |
151 | tree manner. This only effects how the scope tag is handled.</para> | |
152 | ||
153 | <para> | |
154 | The generate configuration has 4 separate sections, each described below.</para> | |
155 | ||
156 | <refsect2><title>Dir Section</title> | |
157 | <para> | |
158 | The <literal>Dir</literal> section defines the standard directories needed to | |
159 | locate the files required during the generation process. These | |
160 | directories are prepended to certain relative paths defined in later | |
161 | sections to produce a complete an absolute path.</para> | |

261 | changed in such a way that does not result in a new contents file | |
262 | [override edit for instance]. A hold off is allowed in hopes that new | |
263 | .debs will be installed, requiring a new file anyhow. The default is 10, | |

464 | the section to force that package to and the final field is the maintainer | |
465 | permutation field.</para> | |
466 | <para>The general form of the maintainer field is: | |
467 | <literallayout>old [// oldn]* => new</literallayout> | |

471 | to be specified. If any of those are found then new is substituted for the | |
472 | maintainer field. The second form unconditionally substitutes the | |
