At the end of the Building_on_Linux document for compiling and installing Sigil, I noticed that the environment variable SKIP_SIGIL_UPDATE_CHECK is listed. This variable isn't in Sigil's launch script, so my assumption is that updating is enabled. But if so, where is the update feature? Surely the updating can't happen automatically in the background, since I had to compile from source to install Sigil. There is also no built-in update feature within Sigil itself that I could find.
