最近在学习stata处理命令，看到这样一份命令，请问大神能否帮忙标注一下各步骤目的与含义啊？
dis "`t'"
quietly {
summ incOUR`t'pc [w=wgt]
local allpc=r(mean)
inequal7 incOUR`t'pc [w=wgt]
local allgini=r(gini)

foreach var of varlist incOUR`t'pc incNBS`t'pc `rent'pc {
  summ `var' [w=wgt]
  local pc=r(mean)
  local share=`pc'/`allpc'*100
  inequal7 `var' [w=wgt]
  local gini=r(gini)
  concindc `var' [w=wgt], welf(incOUR`t'pc)
  noi dis %10s "`var'" %10.1f `pc' %10.2f `share' %10.4f `gini' %10.4f r(concindex) %10.4f r(concindex)*`share'/100
}
}
