+// File-based test framework.
+//
+// This module provides a file-based test framework. The file format is based on
+// that of OpenSSL upstream's evp_test and BoringSSL's aead_test. Each input
+// file is a sequence of attributes, blocks, and blank lines.
+//
+// Each attribute has the form:
+//
+//   Name = Value
+//
+// Either '=' or ':' may be used to delimit the name from the value. Both the
+// name and value have leading and trailing spaces stripped.
+//
+// Blocks are delimited by lines beginning with three hyphens, "---". One such
+// line begins a block and another ends it. Blocks are intended as a convenient
+// way to embed PEM data and include their delimiters.
+//
+// Outside a block, lines beginning with # are ignored.
+//
+// A test is a sequence of one or more attributes followed by a block or blank
+// line. Blank lines are otherwise ignored. For tests that process multiple
+// kinds of test cases, the first attribute is parsed out as the test's type and
+// parameter. Otherwise, attributes are unordered. The first attribute is also
+// included in the set of attributes, so tests which do not dispatch may ignore
+// this mechanism.
+//
+// Functions in this module freely output to |stderr| on failure. Tests should
+// also do so, and it is recommended they include the corresponding test's line
+// number in any output. |PrintLine| does this automatically.
+//
+// Each attribute in a test must be consumed. When a test completes, if any
+// attributes haven't been processed, the framework reports an error.
