NOTE: '/tmp/noise.raw' does NOT exist and that the error must be trapped somewhere but the __system__ one is not trapped.
However jlliagre's post makes sense because I thought it might have generated a syntax error the way I have written it, but it didn't.

NAME
Text::Context - Handle highlighting search result context snippets SYNOPSIS
use Text::Context; my $snippet = Text::Context->new($text, @keywords); $snippet->keywords("foo", "bar"); # In case you change your mind print $snippet->as_html; print $snippet->as_text; DESCRIPTION
Given a piece of text and some search terms, produces an object which locates the search terms in the message, extracts a reasonable-length string containing all the search terms, and optionally dumps the string out as HTML text with the search terms highlighted in bold. new Creates a new snippet object for holding and formatting context for search terms. keywords Accessor method to get/set keywords. As the context search is done case-insensitively, the keywords will be lower-cased. paras @paras = $self->paras($maxlen) Return shortened paragraphs to fit together into a snippet of at most $maxlen characters. as_text Calculates a "representative" string which contains the given search terms. If there's lots and lots of context between the terms, it's replaced with an ellipsis. as_html([ start => "<some tag>", end => "<some end tag>" ]) Markup the snippet as a HTML string using the specified delimiters or with a default set of delimiters ("<span class="quoted">").
