Perl split, but ignoring extra delimiters
Hi all, I'm going bonkers trying to figure something out that is probably simple for most of you. I have a choice between getting therapy for this or coming here to ask for help. I chose the latter. 
What I'm trying to do is perform a split on a line but only one split. For example, let's say I have the following line:
fieldname:this is a sentence: here is another: here is one more.
and the delimiter I want to split on is ":". I want to split this into two strings. The first will contain the value "fieldname". The second will contain the value "this is a sentence: here is another: here is one more."
So the goal is to do a split but just one per line. Any additional delimiters in the line would be ignored. The only thing I've accomplished so far (repeatedly... lol) is getting the second string set to either "this is a sentence" or nothing at all. Is what I'm trying to do possible?
Thanks very much for any tips you can offer.

VOIKKOGC(1) General Commands Manual VOIKKOGC(1) NAME
voikkogc - test program for Voikko grammar checker SYNOPSIS
voikkogc [options] DESCRIPTION
voikkogc is a test program for grammar checking functionality in libvoikko, library of Finnish language tools. It reads sentences or para- graphs from stdin (one per line) and print the results to stdout. The results are structures containing information about grammar errors found in the input paragraph. OPTIONS
--tokenize Instead of looking for grammar errors, split input into tokens. The tokens are prefixed by type: "W" is a word, "P" is punctuation, "S" is whitespace, "U" is unknown and "E" is a prefix for error messages. --split-sentences Instead of looking for grammar errors, split input into sentences. The sentences are prefixed by type: "B" means that end of sen- tence is a probably correct, "P" means that end of sentence is a possibly correct (but probably this and the next identified sen- tence should be joined) and "E" means that sentence ends at the end of input. -n Prefix all grammar checker messages with line number of input data. accept_titles=n accept_unfinished_paragraphs=n accept_bulleted_lists=n Set the value of the specified boolean option. explanation_language=langcode Print human readable error explanation in the specified language. BUGS
Human readable error explanations are printed in UTF-8 regardless of current locale settings. SEE ALSO
