.Sh DESCRIPTION
The file that goes by the name of
.Nm
is a set of commands designed to simplify color logic.
The commands of
.Nm
by themselves are not enough for most uses.
Please refer to the
examples below for the most common situations, and to
.Xr loader 8
for additional commands.
.Pp
Before using any of the commands provided in
.Nm ,
it must be included
through the command:
.Pp
.Dl include color.4th

Add an echo to say we're "Booting..." when the overloaded "boot" Ficl word is executed to better differentiate between loader-specific errors and kernel- specific errors (if ever any of either). This type of functionality hasn't been required before the introduction of the advanced menu system (r222417). Adding this functionality will help different- iate errors at the loader-level such as a BTX halt caused by heap exhaustion and errors that may be involved with executing the kernel (wrong architecture for example). A user can learn that messages before "Booting..." are related to the loader(8) environment and it's Forth-ilk, while those after are not related to loader(8) -- the point that loader(8) has ``left the building''. This patch also includes a man-page update to color.4th(8) as the color logic moves to a lower-level (from being included by beastie.4th to being included by loader.4th). After noticing a delay between execution of the overloaded "boot" FICL word and the display of text on-screen, gcooper confirmed that the introduction of a builtin memory test (disabled by adding hw.memtest.tests="0" to loader.conf(5)) was the cause of the delay. This patch adds an echo to produce "Booting..." when the overloaded "boot" word is executed (this includes from the interactive command-prompt on all arches, from the menu system on arches that run the beastie menu, and even those arches that run the menu but disable it by setting beastie_disable="YES" in loader.conf(5)). When loader_color="YES" in loader.conf(5), the same message is produced but in white text on a blue background (only the letters produced have this background -- opposed to perhaps the entire line).
