+# 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:
#
# We can generate these forms:
#
-# Tiny3:
-# Tiny4:
-# Tiny5:
-# Tiny6:

-# Tiny8:
+# 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
-# Tiny4 1070
-#
-# Tiny4Q:
-# Tiny6Q:
-# Tiny9Q:
-# same but in two lines eg
-# Tiny4Q 10
-# 70
-#
-# Git4 Git4Q
-# Git6 Git6Q
-# Git8 Git8Q
+# Small4 1070
+# If tree is dirty, + or * is suffixed, reducing number of
+# digits by 1.
+#
+# Small4S:
+# Small6S: Small6T:
+# Small8S: Small9T:
+# Small10S:
+# same but split into two lines (S) or three lines (T) eg
+# Small4S 10 Small6t 1
+# 70 07
+# 0*
+#
+# Git4 Git4S
+# Git6 Git6S Git6T
+# Git8 Git8S
+# Git9 Git9T
+# 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.
-# Small4
