-# xxx much of the comment below is TODO
-#
-# Usage:
-#
-# .../commitid.scad.pl [OPTION...] [STRING...] >commitid.scad.new \
-# && mv -f commitid.scad.new commitid.scad
-#
-# Options:
-#
-# --git generate git commit indications, as shown below
-# (this is the default if no strings are requested with -t)
-#
-# --git=object
-# generate git commit indication based on commit object only
-# (ie avoid counting commits)
-#
-# -i do not generate `+' if git-untracked files are present
-#
-# [-t[FORM]] TEXT
-# generate a form FORM containing TEXT
-# TEXT can contain newlines (final newline usually undesirable)
-# if FORM not specified, generates Arg0 Arg1 Arg2 in sequence
-# character set is SPC 0-9 a-f + * (`*' glyph is `=/=').
-#
-# We generate a physical indication of which commit was used.
-#
-# We provide for scaling factors with dynamic variables:
-# $Commitid_pixelsz if not set, we use 0.8 } multiplied
-# $Commitid_scale if not set, we use 1.0 } together
-# $Commitid_depth if not set, we use xy pixel size from above / 2
-# $Commitid_depth_scale if not set, we use 1.0 (multiplies depth above)
-#
-# For each form we have
-#
-# module Commitid_Form_2D() { ... }
-# module Commitid_Form() { ... }
-# function Commitid_Form_sz() => [ x, y ]
-#
-# These have their origin in the bottom left corner. The 3D model
-# is a positive, has its origin halfway through, and is twice the
-# depth in height, so it can be added or subtracted.
-#
-# And we provide
-#
-# function Commitid_pixelsz() // $Commitid_pixelsz * $Commitid_scale
-# function Commitid_depth() // see above
-#
-# We can generate these forms:
-#
-# Small3:
-# Small4:
-# Small5:
-# Small6:
-# Small7:
-# Small8:
-# Small9:
-# Small10:
-# git rev-list --first-parent --count HEAD
-# typically 3-4 characters but we allow for up to 6
-# padded with zeroes; if too long we reduce mod 10^n
-# eg
-# Small4 1070
-# If tree is dirty, + or * is suffixed, reducing number of
-# digits by 1.
-#
-# Small4S:
-# Small6S:
-# Small8S:
-# Small10S:
-# same but split into two lines eg
-# Small4S 10
-# 70
-#
-# Git4 Git4S
-# Git6 Git6S
-# Git8 Git8S
-# Git10 Git10S
-# git-rev-parse HEAD (prefix of requested length)
-# eg
-# Git6 82f2a2
-# If tree is dirty, + or * is suffixed to commitid,
-# reducing number of hex digits by 1.
-
-# Full3
-# Full4
-# Full5
-# Full6
-# Full7
-# Full8
-# Full9
-# Full10
-# git-rev-list --first-parent --count HEAD
-# git-rev-parse HEAD
-# eg
-# Full6 1070
-# 82f2a2
-# If tree is dirty, + or * is suffixed to count (but not to
-# commitid) reducing number of digits by 1.
