The goal is to add tests for *all* functions in libcurl. If functions are too
big and complicated, we should split them into smaller and testable ones.

## Build Unit Tests
'./configure --enable-debug' is required for the unit tests to build. To
`./configure --enable-debug` is required for the unit tests to build. To
enable unit tests, there will be a separate static libcurl built that will be
used exclusively for linking unit test programs. Just build everything as
normal, and then you can run the unit test cases as well.
Run Unit Tests
==============
## Run Unit Tests
Unit tests are run as part of the regular test suite. If you have built
everything to run unit tests, to can do 'make test' at the root level. Or you
can 'cd tests' and 'make' and then invoke individual unit tests with
./runtests.pl NNNN where NNNN is the specific test number.

`./runtests.pl NNNN` where `NNNN` is the specific test number.
Debug Unit Tests
================
## Debug Unit Tests
If a specific test fails you will get told. The test case then has output left
in the log/ subdirectory, but most importantly you can re-run the test again
using gdb by doing ./runtests.pl -g NNNN. That is, add a -g to make it start
up gdb and run the same case using that.

Write Unit Tests
