+# rsc.io/goversion
+
+Goversion scans a directory tree and, for every executable it finds, prints
+the Go version used to build that executable.
+
+Usage:
+
+    goversion [-crypto] [-v] path...
+
+The list of paths can be individual files or directories; if the latter,
+goversion scans all files in the directory tree, not following symlinks.
+
+Goversion scans inside of tar or gzipped tar archives that it finds (named
+`*.tar`, `*.tar.gz`, or `*.tgz`), but not recursively.
+
+The `-crypto` flag causes goversion to print additional information about the
+crypto libraries linked into each executable.
+
+The `-v` flag causes goversion to print information about every file it
+considers.
