Can someone explain this script to me?

B = Input.GetText("Input1");
if B ~= "" then
for k,v in pairs(String.Split(B,"@echo ")) do
token = B
tokenTbl = {}
for j in string.gmatch(token, "(.-)@echo ") do
if j ~= "" then
table.insert(tokenTbl, j);
end
for k,v in pairs(String.Split(B,"@clos ")) do
for j in string.gmatch(token, "(.-)@clos ") do
if (j ~= "") then
table.insert(tokenTbl, j);
end
end
end
end
for count = 1, Table.Count(tokenTbl) do
if (count == 1) then
Paragraph.SetText("Paragraph1", tokenTbl[1]);
elseif (count == 2) then
Paragraph.SetText("Paragraph1", tokenTbl[1]..tokenTbl[2]);
elseif (count == 3) then
Paragraph.SetText("Paragraph1", tokenTbl[1]..tokenTbl[2]..tokenTbl[3]);
elseif (count == 4) then
Paragraph.SetText("Paragraph1", tokenTbl[1]..tokenTbl[2]..tokenTbl[3]..tokenTbl[4]);
elseif (count == 5) then
Paragraph.SetText("Paragraph1", tokenTbl[1]..tokenTbl[2]..tokenTbl[3]..tokenTbl[4]..tokenTbl[5]);
end
end
-- tokenTbl[1]..tokenTbl[2]..tokenTbl[3]..tokenTbl[4]..tokenTbl[5]
end
end
