Hard-coded column with:

<lang txr>@(collect)

Sample run:

<pre>$ txr align-data.txr align-data

Left justified:

Given a text file of many lines, where fields within a line

are delineated by a single 'dollar' character, write a program

that aligns each column of fields by ensuring that words in each

column are separated by at least one space.

Further, allow for each word in a column to be either left

justified, right justified, or center justified within its column.
