Note that solc only allows you to include files from certain directories:
They have to be in the directory (or subdirectory) of one of the explicitly
specified source files or in the directory (or subdirectory) of a remapping
target. If you want to allow direct absolute includes, just add the
remapping `=/`.
If there are multiple remappings that lead to a valid file, the remapping
with the longest common prefix is chosen.

This essentially instructs the compiler to search for anything starting with
`github.com/ethereum/dapp-bin/` under `/usr/local/lib/dapp-bin` and if it does not

the remapping targets and outside of the directories where explicitly specified source
files reside, so things like `import "/etc/passwd";` only work if you add `=/` as a remapping.
If there are multiple matches due to remappings, the one with the longest common prefix is selected.
If your contracts use [libraries](#libraries), you will notice that the bytecode contains substrings of the form `__LibraryName______`. You can use `solc` as a linker meaning that it will insert the library addresses for you at those points:
