What is Sigil?
Sigil is listed in our database as a program that opens or converts the file formats shown on this page. The formats it works with include .EPUB and .OPF.
You can get the official version from the developer's website (code.google.com); we do not host the installer and only point you to the original source. A detailed, hand-checked description of Sigil is on the way; for now the information here comes straight from our database.
