+.TH explode "" "" "/rdb Command"
+.PC "Produce table of subparts and their count for a part"
+\fBexplode \fIPart Amount \fB[ \fItable \fB]\fR
+.PP
+.II "table^explode part"
+.II "explode part into subparts"
+The command
+.B explode
+takes a part number or name and looks it up in a part table
+to find all of its subparts.
+It then finds the subparts of those subparts, and so forth, until
+it can seek no farther.
+.B explode
+also multiplies the number of parts times the subpart
+counts at each interaction, so the final subpart table
+lists all of the subparts of the original part and the
+total number of subparts needed to make the part.
+.PP
+You can use
+.B explode
+to generate a list of all items needed to make a product.
+The cost of these subparts, times the count,
+gives the value that can be totaled to arrive at the total
+cost of the product.
+.PP
+.B explode 
+assumes that the
+.BR Part ,
+.BR Subpart ,
+and
+.B Count
+columns
+are the first three columns of the table, and that the third column
+is actually named
+.BR Count .
+.SH Example
+If you had a
+.B parttable,
+like this:
+.DM
+Part    Subpart Count
+----    ------- ------
+10001   10010   3
+10001   10020   4
+10010   10100   2
+10020   10100   5
+.DE
+.PP
+and you wanted to find the subpart list and count for
+two part 10001s, you would type:
+.DM
+	explode 10001 2
+.DE
+.PP
+The result would be:
+.DM
+Part    Amount
+----    ------
+10001        2
+10010        6
+10020        8
+10100       52
+.DE
+.PP
+Note that both 10010 and 10020 have 10100 as a subpart, but
+.B explode
+uses
+.B subtotal
+to combine the 10100 subparts into one row.
+The table is also sorted.
