+Botan is a BSD-licensed crypto library for C++. It provides applications
+with the ability to use a number of cryptographic algorithms, as well as
+SSL/TLS, X.509 certificates and CRLs, PKCS #10 certificate requests, a
+filter/pipe message processing system, and a wide variety of other
+features.
+
+Botan relies on Python3 for its compilation configuration.
+
+To build TPM support, use `TPM=YES`. This option adds a dependency on
+`system/trousers`.
+
+To build TPM2 support, use `TPM2=YES`. This option adds a dependency on
+tpm2-tss (not on SBo).
+
+This package can be safely installed alongside Botan.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
