Automatic Capitalization of sectioning headings?

Question

Is there anyway to make LaTeX automatically capitalize sectioning headings?

That is, I would like this to generate a capitalized headline:

documentclass{article}
begin{document}
section{This should be in title case.}
But it isn't.
end{document}

Another solution, using any additional package, it to modify the section, subsection etc. macros. It can be done fairly easily with the following

makeatletter
renewcommand{section}{@startsection {section}{1}{z@}%
             {-3.5ex @plus -1ex @minus -.2ex}%
             {2.3ex @plus .2ex}%
             {normalfontLargescshapebfseries}}

renewcommand{subsection}{@startsection{subsection}{2}{z@}%
             {-3.25ex@plus -1ex @minus -.2ex}%
             {1.5ex @plus .2ex}%
             {normalfontlargescshapebfseries}}

renewcommand{subsubsection}{@startsection{subsubsection}{2}{z@}%
             {-3.25ex@plus -1ex @minus -.2ex}%
             {1.5ex @plus .2ex}%
             {normalfontnormalsizescshapebfseries}}
makeatother

The title of the section, subection and subsubsection will then be in small caps.

sectsty provides easy hooks into sectional units. MakeUppercase turns the title into UPPERCASE, while titlecap (from titlecaps) turns it into Title Case.

documentclass{article}
usepackage{sectsty}% http://ctan.org/pkg/sectsty
usepackage{titlecaps}% http://ctan.org/pkg/titlecaps
begin{document}
tableofcontents
sectionfont{MakeUppercase}
section{This should be in upper case}
It is!
sectionfont{titlecap}
section{This should be in title case}
It is!
end{document}

If you're using hyperref, MakeUppercase will break some ToC hyperrefs. You can use latex3 features as an alternative to MakeUppercase, you'll just need to redefine section. MWE:
documentclass{article}

usepackage{xparse}
usepackage{hyperref}
