Jack,
If you use
BeginPackage["PiecewiseContinuous`"]
and put the file into, with Windows
C :
\\ProgramFiles\\WolframResearch\\Mathematica\\4.0\\AddOns\\ExtraPackages
Then
<<PiecewiseContinuous`
will load the package.
I classify my own packags inside ExtraPackages so that, for example it might
appear in
haypacks\\Calculus
and I would have use
BeginPackage["Calculus`PiecewiseContinuous`"]
To load, I would need
<< haypacks`Calculus`PiecewiseContinuous`
If added to the search path (given by $Path) by
AppendTo[$Path,
"C:\\Program Files\\Wolfram
Research\\Mathematica\\4.0\\AddOns\\ExtraPackages\\haypacks"]
Then I would be able to load with
<< Calculus`PiecewiseContinuous`
but then there would be a problem if, say, the StandardPackages included , a
package named PiecewiseContinuous inside the folder named Calculus
This problem can go on and on of course
