The environment is +configured per a provided HorizonScript file. +.Ss Image Creation +The +.Nm +utility first executes the HorizonScript in a temporary directory, called +the +.Em intermediate directory . +From there, the +.Nm +utility then creates the image using the files present in the intermediate +directory. The intermediate directory is not removed after image creation, +allowing inspection of the files used to create the image. +.Ss Image Formats +The +.Nm +utility can be extended with new image formats by writing a new backend. +The backends included with the default distribution include: +.Bl -tag -width Ds +.It tar +Creates a pax-extended ustar archive. See +.Xr 1p pax +for a description of the on-disk format. This archive may be extracted to +the desired system at a later time. +.It tgz, tbz, txz +Creates a pax-extended ustar archive, like tar, but additionally compresses +the archive with +.Xr 1 gzip +(tgz), +.Xr 1 bzip2 +(tbz), or +.Xr 1 xz +(txz). +.El +.Sh OPTIONS +The +.Nm +utility supports the following options: +.Bl -tag -width Ds +.It Fl h +Prints a short help message to the current terminal and exits. +.It Fl i Ar DIRECTORY +Sets the intermediate directory to +.Ar DIRECTORY . +.It Fl n +Disables colour output and ANSI escapes when writing log output.
