+Struktur Tabel Web Register 
+===========================
+
+Web Register adalah istilah untuk pajak yang ditarik oleh pemerintah daerah. Ia
+merupakan kelanjutan sistem Pendapatan Daerah Lainnya (PDL). Kecenderungannya
+di retribusi.
+
+Paket ini selain berisi struktur tabel juga memuat query yang kerap digunakan
+untuk proses:
+
+1. inquiry (cek tagihan)
+2. payment (pembayaran)
+3. reversal (pembatalan pembayaran)
+
+Uji Coba
+--------
+
+Buat file ``test.ini`` seperti contoh berikut ini::
+
+  [main]
+  db_url = postgresql://sugiana:a@localhost/webr
+  persen_denda = 2
+
+Sesuaikanlah pada ``db_url``. Kemudian dapatkan daftar tagihan::
+
+  $ env/bin/webr_available_invoice test.ini
+
+Nanti akan tampil seperti ini #FIXME::
+
+  #1 10241 2019 36.72... ER*** Rp 1.465.200
+  #2 10356 2019 36.72... JU*** Rp 1.500.000
+  #3 10361 2019 36.72... MU*** Rp 1.500.000
+
+Kolom kedua adalah Invoice ID atau sering disebut sebagai nomor bayar. Nomor
+ini bekal untuk inquiry atau cek tagihan::
+
+  $ env/bin/webr_inquiry test.ini --invoice-id=10241
+
+Untuk melanjutkan pembayaran tambahkan opsi ``--payment``::
+
+  $ env/bin/webr_inquiry test.ini --invoice-id=10241 --payment
+
+Sedangkan untuk membatalkannya tambahkan opsi ``--reversal``::
+
+  $ env/bin/webr_inquiry test.ini --invoice-id=10241 --reversal
+
+Selamat mencoba, semoga berhasil.
