# extresso(1)

wrapper for wrestool and icotool

## NAME

extresso - wrapper for wrestool and icotool

## SYNOPSIS

**extresso** \[*OPTIONS*\]... \[*FILE*\]...

## DESCRIPTION

This manual page documents briefly the **extresso** command. This manual page was written for the Debian GNU distribution because the original program does not have a manual page.

Extresso reads resource scripts, and uses wrestool to extract the listed resources and icotool to convert them (if necessary).

## OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (\`-').

- **-o,**--output=DIR

  Where to place extracted files (default \`.').

- **--format=FORMAT**

  Extraction format of icon resources, passed to icotool.

- **-b,**--base=DIR

  Base directory of local files in scripts. (This will be appended to \`\`file'' lines in the scripts.)

- **-i,**--interactive

  Prompt before extraction.

- **-v,**--verbose

  Explain what is being done.

- **--help**

  Display a help message and exit.

- **--version**

  Output version information and exit.

## EXAMPLES

Extract all resources from shell32.dll using the resource script \`\`win98\_shell32'', assuming it is available in \`\`/windows/windows/system/shell32.dll'', and placing output in \`\`out/'':

  $ extresso ../data/resscripts/win98\_shell32 --base=/windows/windows --output=out/\
   $ find out/ -type f \| wc -l\
   339\
   $
