+cproc (small C11 compiler based on QBE)
+
+cproc is a C11 compiler using QBE as a backend. It is released under
+the ISC license. Some C23 features and GNU C extensions are also
+implemented. There is still much to do, but it currently implements
+most of the language and is capable of building software including
+itself, mcpp, gcc 4.7, binutils, and more.
+
+This doesn't support 32-bit x86. It supports x86_64 (tested) and
+aarch64 (untested; if it doesn't work, send me a patch and I'll
+include it).
+
+The build runs cproc's self-test suite. The results will be saved to:
+  /usr/doc/cproc-$VERSION/check-results.txt

+# 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.
