## JINJA
If the envtpl command is available, Jinja templates will also be pro-
cessed to create or overwrite real files. yadm will treat files ending
in
##yadm.j2
as Jinja templates. During processing, the following variables are set
according to the rules explained in the ALTERNATES section:
YADM_CLASS
YADM_OS
YADM_HOSTNAME
YADM_USER
For example, a file named whatever##yadm.j2 with the following content
{% if YADM_USER == 'harvey' -%}
config={{YADM_CLASS}}-{{ YADM_OS }}
{% else -%}
config=dev-whatever
{% endif -%}
would output a file named whatever with the following content if the
user is "harvey":
config=work-Linux
and the following otherwise:
config=dev-whatever
See http://jinja.pocoo.org/ for an overview of Jinja.

To use this feature, a list of patterns must be created and saved as
$HOME/.yadm/encrypt. This list of patterns should be relative to the
configured work-tree (usually $HOME). For example:
.ssh/*.key
.gnupg/*.gpg
The yadm encrypt command will find all files matching the patterns, and
prompt for a password. Once a password has confirmed, the matching
files will be encrypted and saved as $HOME/.yadm/files.gpg. The pat-
terns and files.gpg should be added to the yadm repository so they are
prompt for a password. Once a password has confirmed, the matching
files will be encrypted and saved as $HOME/.yadm/files.gpg. The pat-
terns and files.gpg should be added to the yadm repository so they are
available across multiple systems.
To decrypt these files later, or on another system run yadm decrypt and
provide the correct password. After files are decrypted, permissions
provide the correct password. After files are decrypted, permissions
are automatically updated as described in the PERMISSIONS section.
