+ * Those designated 'file' will be accessed using fopen/fread and must
+ * reference a single file in the 'fmts' element. Entries specifying
+ * 'pipe' will employ popen/fread, their 'fmts' element could contain
+ * many pipelined commands and, none can be interactive.
+ *
+ * Here are some examples of both types of inspection entries.
+ * The first entry will be ignored due to the initial '#' character.
+ * For clarity, the pseudo tab depictions (^I) are surrounded by an
+ * extra space but the actual tabs would not be.
+ *
+ * # pipe ^I Sockets ^I lsof -n -P -i 2>&1
+ * pipe ^I Open Files ^I lsof -P -p %d 2>&1
+ * file ^I NUMA Info ^I /proc/%d/numa_maps
+ * pipe ^I Log ^I tail -n100 /var/log/syslog | sort -Mr
+ *
+ * Caution: If the output contains unprintable characters they will
+ * be displayed in either the ^I notation or hexadecimal <FF> form.
+ * This applies to tab characters as well. So if one wants a more
+ * accurate display, any tabs should be expanded within the 'fmts'.
+ *
+ * The following example takes what could have been a 'file' entry
+ * but employs a 'pipe' instead so as to expand the tabs.
+ *
+ * # next would have contained '\t' ...
+ * # file ^I <your_name> ^I /proc/%d/status
+ * # but this will eliminate embedded '\t' ...
+ * pipe ^I <your_name> ^I cat /proc/%d/status | expand -
+ *
+ * Note: If a pipe such as the following was established, one must
+ * use Ctrl-C to terminate that pipe in order to review the results.
+ * This is the single occasion where a '^C' will not terminate top.
+ *
+ * pipe ^I Trace ^I /usr/bin/strace -p %d 2>&1

+ . To avoid truncation on the main top display, each column header

+ . Those fields shown with a '+' are also eligible for user resizing
+ . using the 'X' command. That means the default width might produce
+ . truncation but need not if widened (see the man page 'X' command).
+ .
+ . All headers are subject to a maximum of 8 on the Fields Management
+ . screen where truncation is entirely acceptable.
+ .
+ . The associated descriptions are always limited to 20 characters,
+ . and are used only on the Fields Management screen.
