-# 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 + *
-#
-# 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)
-# $Commitid_max_best_scale if not set, we use 2.0 (max mult of xy in Best)
-#
-# 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:
-#
-# In each case:
-# if tree is dirty, * is suffixed or prefixed to count or commitid
-# if tree has untracked files, + is added
-# (where it is added depends on the Form; in any case it does not
-# change the size, but steals space from digits)
-#
-# Small2 Small3 ... 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 if the count is 123456
-# Small5 3456*
-# Small8 _*123456 (where _ are spaces)
-# the git objectid is included if it will fit
-# unambiguously and usefully eg
-# Small9 ab*123456
-#
-# Small2S Small4S ... Small10S:
-# Small3T Small9T:
-# same but split into two lines (S) or three lines (T) eg
-# Small4S 45 Small6T _3
-# 6* 45
-# 6*
-#
-# Git2 Git3 ... Git10:
-# Git4S Git6S ... Git10S:
-# Git6T Git9T:
-# git-rev-parse HEAD (prefix of requested length)
-# eg if the commitid is abcdef0123...
-# Git5 abcd*
-
-# Full4 Full6 ... Full20:
-# git-rev-list --first-parent --count HEAD
-# git-rev-parse HEAD
-# (all on two lines)
-# eg
-# Full6 abcdef Full8 abcdef01
-# 23456* _123456*
-#
-# Full6T Full9T ... Full30T
-# as Full but commit is split over two lines
-# for a 3-line message; eg
-# Full9T abc
-# de*
-# 456
-#
-# FontDemo
-#
-# Arg0, Arg1, ...
-# Strings passed on command line
