NAME
concat - Join lists together
SYNOPSIS
concat ?arg arg ...?
_________________________________________________________________
DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing spaces from each of them. If all the
arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments. For example,
the command
concat a b {c d e} {f {g h}}
will return
a b c d e f {g h}
as its result, and
concat " a b {c " d " e} f"
will return
a b {c d e} f
as its result.
If no args are supplied, the result is an empty string.
