-/**
- * The trace API can be used to print debug messages to stderr or a file. Trace
- * code is inactive unless explicitly enabled by setting `GIT_TRACE*` environment
- * variables.
- *
- * The trace implementation automatically adds `timestamp file:line ... \n` to
- * all trace messages. E.g.:
- *
- * ------------
- * 23:59:59.123456 git.c:312               trace: built-in: git 'foo'
- * 00:00:00.000001 builtin/foo.c:99        foo: some message
- * ------------
- *
- * Bugs & Caveats
- * --------------
- *
- * GIT_TRACE_* environment variables can be used to tell Git to show
- * trace output to its standard error stream. Git can often spawn a pager
- * internally to run its subcommand and send its standard output and
- * standard error to it.
- *
- * Because GIT_TRACE_PERFORMANCE trace is generated only at the very end
- * of the program with atexit(), which happens after the pager exits, it
- * would not work well if you send its log to the standard error output
- * and let Git spawn the pager at the same time.
- *
- * As a work around, you can for example use '--no-pager', or set
- * GIT_TRACE_PERFORMANCE to another file descriptor which is redirected
- * to stderr, or set GIT_TRACE_PERFORMANCE to a file specified by its
- * absolute path.
- *
- * For example instead of the following command which by default may not
- * print any performance information:
- *
- * ------------
- * GIT_TRACE_PERFORMANCE=2 git log -1
- * ------------
- *
- * you may want to use:
- *
- * ------------
- * GIT_TRACE_PERFORMANCE=2 git --no-pager log -1
- * ------------
- *
- * or:
- *
- * ------------
- * GIT_TRACE_PERFORMANCE=3 3>&2 git log -1
- * ------------
- *
- * or:
- *
- * ------------
- * GIT_TRACE_PERFORMANCE=/path/to/log/file git log -1
- * ------------
