Description [edit section]

= Description =
ftc query-board can parse an override-func from a board file, but ovgen.py
cannot.

You get the following:

Add the following to bbb.board:
{{{
override_func ov_rootfs_sync() {
    cmd "sync" || abort_job "Unable to flush buffers on target"
    cmd "date $(date +%m%d%H%M%Y.%S)"
}
}}}

And ovgen generates the following error:
(adjust OF_DEBUG_ARGS in scripts/overlay.sh)

{{{#!YellowBox
...
log: discarding string function ov_rootfs_sync() {

log: parsed function ov_rootfs_sync
log: body: function ov_rootfs_sync() {

}
log: function found

Notes [edit section]

= Notes =
The implementation of ovgen.py is needlessly complicated.  Maybe
an ovgen2.py could be written which does the same thing, using code
from ftc (that was written for query-board).

See ftc functions: get_board_vars() and parse_shell_file()

Note that these function don't do test variables, just board
variables with overrides.
