### # nuxfs - Filesystem layout manager
###
### *nuxfs* command uses file structure definition present in *.nuxfs* file
### to understand intented state of directory / filesystem of user.
###
### This definition is not only used to create filesystem hierarchy, checkout
### git repositories but also to verify state of filesystem afterwards.
###
### ## Example of .nuxfs file in home directory
###
### *dir* github
### *git* nux-env https://github.com/tonydamage/nux-env.git
### *git* bats https://github.com/sstephenson/bats.git
### *enddir*
### *link* .bashrc github/nux-env/bashrc
###
### This *.nuxfs* file describes simple home structure. If we execute
### **nuxfs apply** command, it will performs filesystem changes in order to
### recreate structure described in *.nuxfs* file. In case of example it is
### equivalent of executing:
### mkdir -p github
### git clone https://github.com/tonydamage/nux-env.git github/nux-env
### git clone https://github.com/sstephenson/bats.git
