# gwar: git workspaces and repositories
|
||||
|
||||
this is not meant for general consumption!
|
||||
|
||||
i like to be able to quickly bootstrap my git projects when i move into a fresh
|
||||
os install - having a single-file binary to make that happen seemed really
|
||||
nice, plus, i was looking for an excuse to play with rust a bit. you have been
|
||||
warned.
|
||||
|
||||
## building and testing locally
|
||||
|
||||
```bash
|
||||
sudo port install libiconv
|
||||
sudo mkdir /opt/local/include/iconv
|
||||
sudo cp /opt/local/include/iconv.h /opt/local/include/iconv/
|
||||
# building
|
||||
CFLAGS=-I/opt/local/include/iconv cargo build
|
||||
