The documentation for the latest stable version of the XForms library is available in PDF and HTML format (the later as a gzipped tar archive). You can download it as the files xforms.pdf and xforms.html.tar.gz The old documentation, originally meant for version 0.89 but useful up to version 1.0.90, is available in PostScript format. The files to download are forms.ps.gz which is suitable for printers capable of two-sided print (duplex). If your printer can't, you should get forms_sgnl.ps.gz
