# General workings of format strings
#
# A format string (_FMT) contains placeholders, e.g., <<name>>. These
# placeholders are filled with the relevant information. A placeholder may
# occur zero times, once, or more than once. There are two types of
# placeholders: strings and items. A placeholder of type string comes with a
# variable containing a `printf` expression (_FMT_placeholder). This `printf`
# expression may be used to additionally modify the string passed. If the
# string passed is empty, then each corresponding placeholder is replaced
# with the empty string, i.e., the `printf` expression is bypassed. A
# placeholder of the alternative type (item) comes with a series of variables
# that encode constants to be used (_FMT_placeholder_XYZ).
#
# The items in the format string may be separated with "\t". This will induce
# a proper representation (using `column`). By default, all fields but the
# first are left aligned, and the first field is right aligned. This can be
# changed by setting the appropriate FMT_RIGHTALIGN variable. If that
# variable is empty, then the first field is right aligned. This means that
# at least one field must be right aligned.
