* Brief description of environment variables *

COOL_DEBUG              <set/unset>
    if set handles a fatal signal by printing a message
    containing the PID and waiting 30 seconds to allow
    a 'sudo gdb' to be attached.

COOL_LOGLEVEL           <level>
    set the log level & verbosity to <level> - values of
    <level> are one of:
        none (turns off logging), fatal, critical,
        error, warning, notice, information, debug, trace

COOL_NO_AUTOSAVE        <set/unset>
    if set avoids automatic saving of the document being edited.

SLEEPFORDEBUGGER        <seconds to sleep>
    sleep <n> seconds in the broken process after starting in
    order to allow a 'sudo gdb' session to 'attach <pid>' to them.

SLEEPKITFORDEBUGGER     <seconds to sleep>
    sleep <n> seconds in each kit process instance after forking,
    to allow a 'sudo gdb' session to attach and debug that
    process.

SLEEPBACKGROUNDFORDEBUGGER     <seconds to sleep>
    sleep <n> seconds in each kit spawned background save process
    after forking, to allow a 'sudo gdb' session to attach and debug
    that process.

COOL_STORAGE_COOKIE <key:value>
    Sets a cookie to all the requests made to storage. This is extremely
    useful for debugging WOPI implementations. For example:
    Using XDebug with ownCloud/Nextcloud.

COOL_SERVE_FROM_FS
    If mentioned, files are not loaded into the memory on start,
    instead they are read from the filesystem. This can be helpful in
    COOL development where you can tweak it without restarting wsd.

COOL_FORCE_BGSAVE
    If set, force all saves to be done in a background kit process.
