The icoutils programs deal with Microsoft Windows icons and cursors. The included programs are "wrestool", "icotool" and "extresso".
Resources (such as icons and cursors, but not only those) can be extracted from Windows executable and library files with "wrestool". Conversion of these files to XPM images is done with "icotool". "extresso" automates these tasks with the help of special resource scripts.
In the summer of 1998, I wrote a program called icoutil. I wanted to re-use icons found in Windows 98 in icewm. Icewm does not read icon files, but supports .XPM images. icoutil was able to extract XPM images from .ICO files. But the ICO files had to come from somewhere - namely DLL and EXE binaries. I did at that time not know how the structure of these files, but was able to write a program called extrico that used Win32 methods to extract icon resources from such binaries. Because of this it was necessary to run extrico in a Win32 environment.
The program icoutil was later rewritten and replaced with icotool. I also removed extrico, replacing it with wrestool to read DLL and EXE files and extract resources without the need of Windows.
With extresso, that automates these tasks, the icoutils programs were formed. The first version was released in June, 1999.
