1) Term:ANSIColor is a terminal setting.
There is no such thing as "writing bold to a file". You need to write
data that will be interpreted by whatever you intend to use to view
it. for instance, to output html, you would use `print MU
"<strong>text</strong>";`. To write a file you'll read from a
terminal, you need to print the appropriate escape sequence for the
terminal you're using.
2) You have specified `color 'bold'` for the stdout filehandle, but
not the MU filehandle. You can use `print MU color 'bold'` to cause
the escape sequence (probably \e[1m) to be written to file. Note,
though, that this will not be protable, and printing the escape
sequence to screen on any terminal other than the one intended can
cause unintended results and require you reset the connection.
Embedding escape sequences in files is a bad idea. It's much better
to use some kind of markup, and write a program to parse the markup
and output the correct, site-specific escapes when the data is read,
e.g., `print color 'bold' if =~ /<bold>;`
Also, don't forget to turn `color` off, or your screen will remain
bold, even after the program exits.
