# The semantics for the platforms is that every item is checked against the
# environment. For the negative items ("!FOO"), if any of them is false
# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
-# used. For the positive itms, if all of them are false in the environment,
+# used. For the positive items, if all of them are false in the environment,
# the corresponding symbol can't be used. Any combination of positive and
# negative items are possible, and of course leave room for some redundancy.
# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.

+# with a different variant tag.
+#
+# For example, with a target definition that includes:
+#
+# shlib_variant => "-opt",
+#
+# we build the following objects:
+#
+# $ perl -le '
+# for (@ARGV) {
+# if ($l = readlink) {

+# libcrypto.so -> libcrypto-opt.so.1.1
+# libssl-opt.so.1.1
+# libssl.so -> libssl-opt.so.1.1
+#
+# whose SONAMEs and dependencies are:
+#
+# $ for l in *.so; do
+# echo $l
+# readelf -d $l | egrep 'SONAME|NEEDED.*(ssl|crypto)'
+# done
+# libcrypto.so
+# 0x000000000000000e (SONAME) Library soname: [libcrypto-opt.so.1.1]
+# libssl.so
+# 0x0000000000000001 (NEEDED) Shared library: [libcrypto-opt.so.1.1]
+# 0x000000000000000e (SONAME) Library soname: [libssl-opt.so.1.1]
+#
+# We case-fold the variant tag to upper case and replace all non-alnum
+# characters with "_". This yields the following symbol versions:
+#
+# $ nm libcrypto.so | grep -w A
+# 0000000000000000 A OPENSSL_OPT_1_1_0
