+Emscripten is a toolset which allows compiling C/C++ into JavaScript.
+
+
+If that does not scare you, read further.
+
+Emscripten used to work like a compiler-wrapper around gcc/g++/clang,
+and other tools, and doing that now is still possible, via a package
+called "emscripten" (not available at SBo). However, since the
+ambitions of the authors began to grow, more and more tools were
+becoming part of the Emscripten toolset, and it became more and more
+unwieldy installing all of them by hand.
+
+This package, emsdk, is a set of "blessed" shell scripts to do just
+that in a standardised fashion. It might be compared to an Android
+SDK manager, or MinGW installer.
+
+Activate it by sourcing /etc/profile.d/emsdk_env.sh , or run
+individual commands by emsdk <command>

+# 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.

+emsdk: emsdk (simple interface for installing emscripten toolchain)
+emsdk:
+emsdk: The Emscripten SDK is effectively a small package manager for tools
+emsdk: that are used in conjunction with Emscripten.
+emsdk:
+emsdk: The SDK provides a way to install all the required tools, such as
+emsdk: Clang, Python and Node.js along with an update mechanism that
+emsdk: enables migrating to newer Emscripten versions as they are released.
