* Documentation: Remove XHTML spec and fix errors None of the docs follow the XHTML specification, which means that programs that expect this (such as Gnome Web) as it is advertised as such, will completely fail to parse it as it is incorrect syntax. So it is removed. * Remove .chm files

<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
|
|
<meta name="description" content="VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>
