# dwww-index++(8)

build index of registered Debian documentation.

## NAME

dwww-index++ - build index of registered Debian documentation.

## SYNOPSIS

**dwww-index++** \[**-f**\] \[**-i**\] \[**-l**\] \[**-v**\] \[**--** *swish\_option* \[*...*\]\]

## DESCRIPTION

**dwww-index++** is part of the dwww package, which provides access to on-line documentation on a Debian system via WWW.

**dwww-index++** uses  [**index++**(1)](/index++/1.md) program from swish++ package to generate index of Debian documentation files registered with doc-base.

## OPTIONS

- **-f**

  Force generation of the full documentation index even if it is disabled in the configuration file.

- **-i**

  Force generation of the incremental documentation index even if it is disabled in the configuration file.

- **-l**

  Print a list of files which would be indexed on standard output. Can be used together with  **-f** or **-i** to show files which would be indexed by full or incremental indexing.

- **-v**

  Be more verbose.

- **--**

  Any option after  **--** is passed directly to [**index++**(1)](/index++/1.md).\
   For example to see which files are indexed, use

  ```
  dwww-index++ -- -v4
  ```

## CONFIGURATION FILE ITEMS

- DWWW\_INDEX\_DOCUMENTATION

  If this variable is set to **yes** (default), then the documentation index is generated. This setting can be overridden with the **-f** option.

- DWWW\_MERGE\_MAN2HTML\_INDEX

  If this variable is set to  **yes**, then index of registered documentation files will be merged with index of man pages generated by the man2html package (if it is available).

- DWWW\_INDEX\_FULL\_TIME\_INTERVAL

  Specifies how often (in days)  [**dwww-index++**(8)](/dwww-index++/8.md) will generate full index of documentation.  The default value is  **28**.

- DWWW\_INDEX\_INCREMENTAL\_TIME\_INTERVAL

  Specifies how often (in days)  [**dwww-index++**(8)](/dwww-index++/8.md) will run incremental indexing of new documentation files. The default value is  **7**.

## FILES
