+% These functions allow the rescanning of tokens: re-apply \TeX{}'s
+% tokenization process to apply category codes different from those
+% in force when the tokens were absorbed. Whilst this functionality is
+% supported, it is often preferable to find alternative approaches
+% to achieving outcomes rather than rescanning tokens (for example
+% construction of token lists token-by-token with intervening category
+% code changes or using \cs{char_generate:nn}).

+% Sets \meta{tl~var} to contain \meta{tokens}, applying the category
+% code r\'{e}gime specified in the \meta{setup} before carrying out
+% the assignment. (Category codes applied to tokens not explicitly covered
+% by the \meta{setup} are those in force at the point of use of
+% \cs{tl_set_rescan:Nnn}.)
+% This allows the \meta{tl~var} to contain material
+% with category codes other than those that apply when \meta{tokens}
+% are absorbed. The \meta{setup} is run within a group and may
+% contain any valid input, although only changes in category codes,
+% such as uses of \cs{cctab_select:N},
+% are relevant. See also \cs{tl_rescan:nn}.

+% The \meta{tokens} are first turned into a string (using

+% with character code \tn{newlinechar} (set equal to
+% \tn{endlinechar} unless that is equal to $32$, before the user
+% \meta{setup}), then it is split into lines at these characters,
+% then read as if reading multiple lines from a file, ignoring
+% spaces (catcode $10$) at the beginning and spaces and tabs
+% (character code $32$ or $9$) at the end of every line.
+% Otherwise, spaces (and tabs) are retained at both ends of the
+% single-line string, as if it appeared in the middle of a line

+% Rescans \meta{tokens} applying the category code r\'{e}gime

+% such as uses of \cs{cctab_select:N},
+% are relevant. See also \cs{tl_set_rescan:Nnn}, which is more
+% robust than using \cs{tl_set:Nn} in the \meta{tokens} argument of
+% \cs{tl_rescan:nn}.

+% The \meta{tokens} are first turned into a string (using

+% read from a file.
+%
+% Contrarily to the \tn{scantokens} primitive, \cs{tl_rescan:nn}
+% tokenizes the whole string in the same category code regime rather
+% than one token at a time, so that directives such as \tn{verb}
+% that rely on changing category codes will not function properly.
