+# A gentle introduction to flags handling in autosetup
+#
+# Reference: https://msteveb.github.io/autosetup/developer/
+#
+# All configure flags must be described in one or more calls to
+# autosetup's [options] and [options-add] functions. The general
+# syntax of the single argument to those functions is a list contain
+# a mapping of flags to help text:
+#
+#  FLAG => {Help text}
+#
+# Where FLAG can have any of the following formats:
+#
+#   boolopt            => "a boolean option which defaults to disabled"
+#   boolopt2=1         => "a boolean option which defaults to enabled"
+#   stringopt:         => "an option which takes an argument, e.g. --stringopt=value"
+#   stringopt:DESCR    => As for stringopt: with a description for the value
+#   stringopt2:=value  => "an option where the argument is optional and defaults to 'value'"
+#   optalias booltopt3 => "a boolean with a hidden alias. --optalias is not shown in --help"
+#
+# Autosetup does no small amount of specialized handling for flags,
+# especially booleans. Each bool-type --FLAG implicitly gets
+# --enable-FLAG and --disable-FLAG forms. That can lead lead to some
+# confusion when writing help text. For example:
+#
+#   options { json=1 {Disable JSON functions} }
+#
+# The reason the help text says "disable" is because a boolean option
+# which defaults to true is, in the --help text, rendered as:
+#
+#   --disable-json          Disable JSON functions
+#
+# Whereas a bool flag which defaults to false will instead render as:
+#
+#   --enable-FLAG
+#
+# Non-boolean flags, in contrast, use the names specifically given to
+# them in the [options] invocation. e.g. "with-tcl" is the --with-tcl
+# flag.
+#
+# Fetching values for flags:
+#
+#   booleans: use one of:
+#     - [opt-bool FLAG] is autosetup's built-in command for this, but we
+#       have some convenience variants:
+#     - [proj-opt-truthy FLAG]
+#     - [proj-opt-if-truthy FLAG {THEN} {ELSE}]
+#
+#   Non-boolean (i.e. string) flags:
+#     - [opt-val FLAG ?default?]
+#     - [opt-str ...] - see the docs in ./autosetup/autosetup
+#
+# [proj-opt-was-provided] can be used to determine whether a flag was
+# explicitly provided, which is often useful for distinguishing from
+# the case of a default value.

+set allFlags {
+# Structure: a list of M {Z} pairs, where M is a descriptive
+# option group name and Z is a list of X Y pairs. X is a list of
+# $buildMode name(s) to which the Y flags apply, or {*} to apply
+# to all builds. Y is a {block} in the form expected by
+# autosetup's [options] and [options-add] command.  Each block
