+== NAME
+
+hashboot - allows you to execute files from compiled languages as scripts.
+
+== SYNOPSIS
+
+*hashboot* _index_|_check_|_recover_
+
+== DESCRIPTION
+
+hashboot hashes all files in `/boot` and the MBR to check them during early
+boot. It is intended for when you have encrypted the root partition but not the
+boot partition. The checksums and a backup of the contents of `/boot` are stored
+in `/var/lib/hashboot` by default. If a checksum doesn't match, you have the
+option to restore the file from backup.
+
+If there is a core- or libreboot bios and flashrom installed, **hashboot** can
+check bios for modifications too.
+
+== OPTIONS
+
