.SH FORMAT MODULE - format.pm
This module provides a set of macros for formating strings and
numbers.
.PP
The format module provides the following macros:
.TP
.BR "printf(format, arg1, arg2, ...)"
The \fBprintf\fP macro behaves in the same way as the Perl/C function
printf. It takes in a format string followed by a list of arguments
to print. See the \fBprintf\fP(3) man page or Perl documentation for
full details of the \fBprintf\fP function.
.TP
.BR "toupper(string)"
Converts input string to upper case.
.TP
.BR "toupperfirst(string)"
Converts first character of input string to upper case.
.TP
.BR "tolower(string)"
Converts input string to lower case.
.TP
.BR "tolowerfirst(string)"
Converts first character of input string to lower case.
.TP
.BR "substr(string, offset, length)"
Extracts a substring from input \fIstring\fP. \fBsubstr\fP behaves in
the same way as the Perl substr function. \fIoffset\fP is used to
specifiy the first character of the string to output (negative for
offset from end of string), \fIlength\fP is the length of the string
to output. If length is omitted everything from the offset is
returned. For further information on \fBsubstr\fP see the Perl
documentation.
.PP
The format macros are implemented using the \fBfunction.pm\fP module.
