+ * This header contains trace macro definitions, which map trace points within
+ * the code to krb5int_trace() calls with descriptive text strings.
+ *
+ * A new trace macro must be defined in this file for each new location to
+ * be traced; the TRACE() macro should never be used directly.  This keeps
+ * the tracing logic centralized in one place, to facilitate integration with
+ * alternate tracing backends such as DTrace.
+ *
+ * Trace logging is intended to aid power users in diagnosing configuration
+ * problems by showing what's going on behind the scenes of complex operations.
+ * Although trace logging is sometimes useful to developers, it is not intended
+ * as a replacement for a debugger, and it is not desirable to drown the user
+ * in output.  Observe the following guidelines when adding trace points:
+ *
+ *   - Avoid mentioning function or variable names in messages.
+ *
+ *   - Try to convey what decisions are being made and what external inputs
+ *     they are based on, not the process of making decisions.
+ *
+ *   - It is generally not necessary to trace before returning an unrecoverable
+ *     error.  If an error code is unclear by itself, make it clearer with
+ *     krb5_set_error_message().
+ *
+ *   - Keep macros simple.  Add format specifiers to krb5int_trace's formatter
+ *     as necessary (and document them here) instead of transforming macro
+ *     arguments.
+ *
+ *   - Like printf, the trace formatter interface is not type-safe.  Check your
+ *     formats carefully.  Cast integral arguments to the appropriate type if
+ *     they do not already patch.
+ *
+ * The following specifiers are supported by the formatter (see the
+ * implementation in lib/krb5/os/trace.c for details):
+ *
+ *   {int}         int, in decimal
+ *   {long}        long, in decimal
+ *   {str}         const char *, display as C string
+ *   {lenstr}      size_t and const char *, as a counted string
+ *   {hexlenstr}   size_t and const char *, as hex bytes
+ *   {hashlenstr}  size_t and const char *, as four-character hex hash
+ *   {raddr}       struct remote_address *, show socket type, address, port
+ *   {data}        krb5_data *, display as counted string
+ *   {hexdata}     krb5_data *, display as hex bytes
+ *   {errno}       int, display as number/errorstring
+ *   {kerr}        krb5_error_code, display as number/errorstring
+ *   {keyblock}    const krb5_keyblock *, display enctype and hash of key
+ *   {key}         krb5_key, display enctype and hash of key
+ *   {cksum}       const krb5_checksum *, display cksumtype and hex checksum
+ *   {princ}       krb5_principal, unparse and display
+ *   {ptype}       krb5_int32, krb5_principal type, display name
+ *   {patypes}     krb5_pa_data **, display list of padata type numbers
+ *   {etype}       krb5_enctype, display shortest name of enctype
+ *   {etypes}      krb5_enctype *, display list of enctypes
+ *   {ccache}      krb5_ccache, display type:name
