Conditionally include components in a package

[jdlinke]

I'm in the beginning stages of developing a set of three components. Two of them are dependent upon other packages that an end-user programmer may or may not have installed (richmemopackage and SynEdit).

Is there a way to determine whether a particular package has been installed, and to create conditional statements based upon whether this is true or false? Then I can simply not include/register the individual components that wouldn't work if the dependency isn't first installed.

This seems like an easy task, but I haven't been able to find info on how to accomplish it.

Thanks for any help y'all can provide.

No. Create more than one package instead. Make it like this:
if:
A: the independent package
B: the package that depends on C
C: the dependant package
then
B depends on A and C

So, even if C is not installed, people can still install A without installing B.

Thanks for the reply. I was hoping there was a way to just automate the whole process so it was all one step and transparent, but this'll be fine.

Just need to split my package up now.
