Where I'm working, we're using Maven 2 and we have a pretty nice archetype for our projects. The goal was to obtain a good separation of concerns, thus we defined a project structure using multiple modules (one for each application 'layer'):

In vi:
<esc> :set noai
<paste all you want>
<esc> :set ai
In vim:
<esc> :set paste

In plain vi, you probably have `autoindent` on. To turn it off:
<esc> :set noai
<paste all you want>
<esc> :set ai
In vim, you can use the [`paste`](http://www.vim.org/htmldoc/options.html#'paste') option which also sets other options such as `textwidth` and `wrapmargin` to paste-friendly defaults:

If you're after some trend analysis, does it really mean anything to measure beyond SLOC?

You can achieve that using HTA and vbscript. Just call an external tool to do the screenshotting. I forgot what the name is, but on Vista there is a tool to do screenshots. You don't even need an extra install for it.

This is a total shot in the dark since I haven't used ASP at all.
I've been just learning XAML and WPF, which appears to be very similar to what you've posted above and I know that for some UI controls you need to specify the binding mode to two-way in order to get updates in both directions. |

Use ctrl-V ctrl-M to enter a literal ctrl-M into your grep string. so:
grep -IUr --color "^M"
will work - if the ^M there is a literal ctrl-M that you input as I suggested.
If you want the list of files, you want to add the -l option as well. |

There is a cost associated with calling across the JNI boundary.
If you could move the loop that calls exp() into the native code as well, so that there is just one native call, then you might get better results, but I doubt it will be significantly faster than the pure Java solution.
