While String::Util does have a \f(CW\*(C`trim\*(C'\fR function, it depends on Debug::ShowStuff, which depends on Taint, which fails the test suite, and doesn't appear to be maintained. This module installs, is actively maintained, and has no non-core dependencies. .PP Other options include Text::Trim and String::Strip (which is implemented in \s-1XS,\s0 and is therefore likely to be very fast, but requires a C compiler). .SH "AVAILABILITY" .IX Header "AVAILABILITY" The latest version of this module is available from the Comprehensive Perl Archive Network (\s-1CPAN\s0).
