+# Maintainer: Constantine Evans <const@costi.eu>
+#
+# Note: you probably want to install the binary version of NUPACK 4, not this source build.  See below for
+# more details.
+#
+# NUPACK is available under a restricted license that is largely similar to the BSD 3-clause license, updated
+# to address web applications, but with the notable exception that it allows for use and redistribution 
+# "non-commercial academic purposes only".  Furthermore, access to the downloads requires requires a username
+# and password that can be obtained through (free) registration, and sources and binary wheels are intentionally
+# not in PyPI.  While the license appears to allow for redistribution, in the interest of following the authors' 
+# wishes, this PKGBUILD does provide the source code automatically.
+#
+# To use this PKGBUILD, if you can agree to the non-commercial academic license, register for a username and 
+# password at https://www.nupack.org/downloads, download the NUPACK 4 zip file there, and place the zip file 
+# in the same directory as this PKGBUILD.
+#
+# Note that this PKGBUILD is for *source* installation, which may be significantly more complicated than simply
+# installing a binary wheel, also available from the Nupack website.  The intention of this PKGBUILD is to attempt
+# to make source installation work smoothly in Arch Linux, using Arch and AUR packages as much as possible, and
+# allowing installation in circumstances (for example, more recent Python versions) where binary wheels may not
+# be suitable.  The PKGBUILD makes certain changes to the build process:
+#
+# - The default build process uses a bundled vcpkg to build and install a number of external dependencies.  This
+#   build process did not work on Arch the last time I tried it.  The PKGBUILD removes vcpkg from the build process
+#   entirely, and instead uses Arch and AUR packages.  In many cases, this means that newer versions of those
+#   dependencies are used than in the normal build process, which may cause breakages.
+# - NUPACK 4 relies on an older version of TBB, and newer versions removed parts of the API it uses.  This PKGBUILD
+#   thus requires an older version of TBB, which may cause problems for other packages on your system.
+# - One error message in NUPACK 4 does not work well with newer versions of spdlog and fmt, and so is commented out.
+# - SIMD support is currently disabled, as (a) libsimdpp is not currently in the AUR, and (b) when installed (I have
+#   a PKGBUILD for it locally), NUPACK 4 has build errors wwhen NUPACK_SIMD=ON that I don't currently understand.
