Attachments: Allow user-chosen directory and inheritance
The directory used for attachments to an entry is by default chosen automatically, with a name derived from the entry ID to make sure it is unique. However, in some cases it may be better to assign a user-chosen directory to and entry, to be used for attachments. This commits implements this change. See the documentation changes for information on how things work. Thanks to Jason Jackson for pushing this part. The second change made bu this commit is that it is now possible to inherit the attachment directory from a parent, so that an entire project subtree can use a single directory.

*** The attachment directory may now be chosen by the user
|
||||
|
||||
Instead of using the automatic, unique directory related to
|
||||
the entry ID, you can also use a chosen directory for the
|
||||
attachments of an entry. This directory is specified by the
|
||||
ATTACH_DIR property. You can use `C-c C-a s' to set this
|
||||
property.
|
||||
|
||||
*** You can use a single attachment directory for a subtree
|
||||
|
||||
By setting the property ATTACH_DIR_INHERIT, you can now tell
|
||||
Org that children of the entry should use the same directory
|
||||
for attachments, unless a child explicitly defines its own
|
||||
directory with the ATTACH_DIR property. You can use the
|
||||
command `C-c C-a i' to set this property in an entry.
|
||||

||||
