The /opt/freecalypso host directory tree used by the present FC host tools package and by various add-ons to it does NOT follow the traditional Unix/Linux file system hierarchy standard (FHS), instead it is a highly specialized directory tree that is meant to be private to FreeCalypso, with its structure defined solely by the Mother and no one else. The following subdirectories are currently defined: aud-*: these directories appear if you install our optional fc-audio-config package, and contain subtrees to be uploaded by production line scripts into target device FFS under /aud via fc-fsio. batteries and charging: these subtrees come from fc-battery-conf (optional just like fc-audio-config) and are meant to be used with fc-fsio write-battery-table and write-charging-config commands. bin and include are the only subdirectories under /opt/freecalypso which follow traditional UNIX directory layout; include was added so that packages external to the core FC host tools package like fc-rfcal-tools and freecalypso-ui-dev can use rvinterf headers. gcc: the recommend install location for our ARM7 gcc toolchain is /opt/freecalypso/gcc. helpfiles subdir contains help files for those FC host utilities which implement a help command. loadtools subdir contains hardware parameter files and init scripts which underlie the all-important -h option to fc-loadtool, fc-iram and fc-xram, collectively known as loadtools. rfcal subdir only appears if you are doing RF calibration and install fc-rfcal-tools, and some of the necessary config files under that subdir you have to create yourself using your own RF knowledge specific to your particular setup. target-bin contains ARM7 target binaries used under the hood by loadtools. The basic minimal form of the /opt/freecalypso tree is populated when you install FC host tools, but it is further enriched if and when you install further add-ons (fc-audio-config, fc-battery-conf, fc-rfcal-tools) which are more specialized and not required for all users. I expect to have more additions in the future: for example, when we start using the Melody E1 mechanism in our planned FC Libre Dumbphone, there will be a FreeCalypso ringtones package that will install E1-format melody files somewhere under /opt/freecalyso, to be subsequently uploaded into the actual phones via fc-fsio, initially at production time and optionally by end users.
