- Command line syntax

### Purpose

`aiftool` creates an application information file, extension `.aif`, using information contained in a resource file and an EPOC multi-bitmap icon file.

### Command line syntax

  `aiftool` resource-file icon-file

For information about how to interpret the syntax, see BNF grammars.

##### Arguments

resource-file | A file that specifies the captions for all supported languages, the application capabilities, and the number of icons to be included in the `.aif` file.
icon-file | An EPOC multi-bitmap file that contains the icons and icon masks for displaying the application at different sizes.

##### Notes

- The command line syntax and brief notes may be obtained by typing `aiftool` on the command line.
- The resource-file extension, `.rss`, is added by `aiftool`, and must not be specified.
- There is no standard filename extension for an EPOC multi-bitmap file so the icon-file extension must be specified. Usually it is specified as `.mbm`.
