 In Tomo, a shared library is built out of a *directory* that contains multiple
 `.tm` files. Each `.tm` file in the directory (excluding those that start with
 an underscore) will be compiled and linked together to produce a single
-`libwhatever.so` file and `whatever.h` file that can be used by other Tomo
-projects. You can build a library by running `tomo -L dirname/` or `tomo -L` in

 ### Installing
 
 If you additionally add the `-I` flag, Tomo will copy the entire directory
 (excluding files and directories that begin with `.` such as `.git`) into
 `~/.local/share/tomo/installed/` and create a symbolic link for the library's
-`.so` file in `~/.local/share/tomo/lib/`.
