Major layout change to the packages directory
Having one monolithic packages directory makes it hard to find things and is generally overwhelming. This commit splits it into several logical sections roughly based on function, recipes.txt gives more information about the classifications used. The opportunity is also used to switch from "packages" to "recipes" as used in OpenEmbedded as the term "packages" can be confusing to people and has many different meanings. Not all recipes have been classified yet, this is just a first pass at separating things out. Some packages are moved to meta-extras as they're no longer actively used or maintained.

449+
450+<CODE>time</CODE> uses a <EM>format string</EM> to determine which information to
451+display about the resources used by the command it runs. See section <A HREF="time.html#SEC3">1.2 The Format String</A>, for the interpretation of the format string contents.
452+</P>
453+<P>
454+
455+You can specify a format string with the command line options listed
456+below. If no format is specified on the command line, but the
457+<CODE>TIME</CODE> environment variable is set, its value is used as the format
458+string. Otherwise, the default format built into <CODE>time</CODE> is used:

525+The <EM>format string</EM> controls the contents of the <CODE>time</CODE> output.

531+A backslash introduces an <EM>escape</EM>, which is translated
532+into a single printing character upon output. The valid escapes are
533+listed below. An invalid escape is output as a question mark followed
534+by a backslash.

555+<CODE>time</CODE> always prints a newline after printing the resource use

557+character (or `<SAMP>\n</SAMP>').
558+</P>
559+<P>
560+
561+A resource specifier consists of a percent sign followed by another
562+character. An invalid resource specifier is output as a question mark
563+followed by the invalid character. Use `<SAMP>%%</SAMP>' to output a literal
564+percent sign.
565+</P>
566+<P>
567+
568+The resource specifiers, which are a superset of those recognized by the
569+<CODE>tcsh</CODE> builtin <CODE>time</CODE> command, are listed below. Not all
570+resources are measured by all versions of Unix, so some of the values
571+might be reported as zero (see section <A HREF="time.html#SEC10">1.5 Accuracy</A>).

941+<!--docid::SEC10::-->
942+<P>
943+
944+The elapsed time is not collected atomically with the execution of the
945+program; as a result, in bizarre circumstances (if the <CODE>time</CODE>
946+command gets stopped or swapped out in between when the program being
947+timed exits and when <CODE>time</CODE> calculates how long it took to run), it
948+could be much larger than the actual execution time.
949+</P>
950+<P>
951+
952+When the running time of a command is very nearly zero, some values
953+(e.g., the percentage of CPU used) may be reported as either zero (which
954+is wrong) or a question mark.
955+</P>
956+<P>
957+
958+Most information shown by <CODE>time</CODE> is derived from the <CODE>wait3</CODE>
959+system call. The numbers are only as good as those returned by
960+<CODE>wait3</CODE>. Many systems do not measure all of the resources that
961+<CODE>time</CODE> can report on; those resources are reported as zero. The
962+systems that measure most or all of the resources are based on 4.2 or
963+4.3BSD. Later BSD releases use different memory management code that
964+measures fewer resources.
965+</P>
966+<P>
967+
968+On systems that do not have a <CODE>wait3</CODE> call that returns status
969+information, the <CODE>times</CODE> system call is used instead. It provides
970+much less information than <CODE>wait3</CODE>, so on those systems <CODE>time</CODE>
971+reports most of the resources as zero.
972+</P>
973+<P>
974+
975+The `<SAMP>%I</SAMP>' and `<SAMP>%O</SAMP>' values are allegedly only &quot;real&quot; input
976+and output and do not include those supplied by caching devices. The
977+meaning of &quot;real&quot; I/O reported by `<SAMP>%I</SAMP>' and `<SAMP>%O</SAMP>' may be
978+muddled for workstations, especially diskless ones.
