The general syntax for string and id directives is %(name:a:w)

The alignment specifier is a single character: Either \"l\",
\"r\", or \"c\" may be given to specify left, right and

+ positive integer. Both \"a\" and \"w\" are optional.
- A string directive supported by adu is \"dirname\" which is
- subsitituted by the name of the directory. It is available
+ One string directive supported by adu is \"dirname\" which is
+ substituted by the name of the directory. It is available
if either user_list or global_list mode was selected via
--select-mode.
Examples:
+ Print dirname without any padding:
- \"%(diname)\" # print dirname without any padding
- \"%(dirname:c:20)\" # center dirname in a 20 chars wide field
+ \"%(diname)\"
- The other two types of directives, count and size, are used
- for numbers. The syntax for these is %(name:a:w:u). The \"a\"
- and the \"w\" specifier have the same meaning as for the string
- and id directives. The additional \"u\" specifier selects a unit
- in which the number that corresponds to the directive should
- be formated. All three specifiers are optional.
+ Center dirname in a 20 chars wide field:
+
+ \"%(dirname:c:20)\"
+
+ The count and size directives are used for non-negative
+ numbers. The syntax for these is %(name:a:w:u). The \"a\" and
+ the \"w\" specifiers have the same meaning as for the string
+ and id directives. The additional \"u\" specifier selects a
+ unit in which the number that corresponds to the directive
+ should be formated. All three specifiers are optional.
Possible units are the characters of the set \" bkmgtBKMGT\"
specifying bytes, kilobytes, megabytes, gigabytes and
tab character for these combinations respectively.
Examples:
+ Print size in gigabytes right-aligned:
+ \"%(size:r::G)\"
+
+ As before, but use 5 char wide field:
+ \"%(size:r5::G)\"
+
+ As before, but suppress trailing \"G\":
+ \"%(size:r5::*G)\"
+
+
+ The following list contains all directives known to adu,
