Creation of rebuild environments
New environment is created with rbld create:
[test@rebuild-fedora23-1 ~]$ rbld create --base ubuntu:15.10 ubuntu1510

...
Successfully created ubuntu1510:initial
ubuntu:15.10 in this example is a name of Ubuntu 15.10 image from Docker Hub's.
Or:
[test@rebuild-fedora23-1 ~]$ rbld create --basefile alpine34.tar.gz alpine34
Building environment...

Successfully created alpine34:initial
alpine34.tar.gz in this example is a name of archive with compressed file system snapshot of Alpine Linux 3.4.
Created or deployed environment may be modified with rbld modify. Just as running environments there are two modes.
You can modify the environment in immediate mode with rbld modify [ENV] -- [COMMAND]:
[test@rebuild-fedora23-1 ~]$ rbld modify ubuntu1510 -- \
"sudo apt-get update && \
sudo apt-get install -y gcc"
Initializing environment [.....]
>>> rebuild env ubuntu1510:initial-M
>>> sudo apt-get update && sudo apt-get install -y gcc

Processing triggers for libc-bin (2.21-0ubuntu4.3) ...
<<< rebuild env ubuntu1510:initial-M
You can modify the environment in interactive mode with rbld modify [ENV]:
[test@rebuild-fedora23-1 ~]$ rbld modify ubuntu1510:initial
Initializing environment [.....]
>>> rebuild env ubuntu1510:initial-M interactive
>>> Press CTRL-D do leave
test@ubuntu1510:initial-M:~$
Environment-wide variables may be defined via rebuild.rc:
[test@rebuild-fedora23-1 ~]$ rbld modify ubuntu1510:initial
Initializing environment [.....]
>>> rebuild env ubuntu1510:initial-M interactive
>>> Press CTRL-D do leave
test@ubuntu1510:initial-M:~$ sudo vi /rebuild/rebuild.rc
test@ubuntu1510:initial-M:~$ cat /rebuild/rebuild.rc
# This is the rebuild environment definition file.
# Define required environment variables here.
#
# NOTE: Make sure to prefix definitions with
# 'export' directive, i.e.
#export MY_PATH=/path/to/some/location
export CC=clang
test@ubuntu1510:initial-M:~$ exit
<<< rebuild env ubuntu1510:initial-M
List of modified environments may be viewed with rbld status:
[test@rebuild-fedora23-1 ~]$ rbld status
modified: ubuntu1510:initial
Modified environment is committed with new tag by rbld commit:
[test@rebuild-fedora23-1 ~]$ rbld commit --tag v001 ubuntu1510:initial
Creating new environment ubuntu1510:v001...
Instead of committing one may revert environment changes by rbld checkout:
[test@rebuild-fedora23-1 ~]$ rbld checkout ubuntu1510:initial
Committed environment may be deleted with rbld rm:
[test@rebuild-fedora23-1 ~]$ rbld rm ubuntu1510:initial
