Creating .info files to be used with tree

Question

man tree¹ states:

-info Prints file comments found in .info files. See .INFO FILES below for more information on the format of .info files.

and further

.INFO FILES

.info files are similiar to .gitignore files, if a .info file is found while scanning a directory it is read and added to a stack of .info information. Each file is composed of comments (lines starting with hash marks (#),) or wild-card patterns which may match a file relative to the directory the .info file is found in. If a file should match a pattern, the tab indented comment that follows the pattern is used as the file comment. A comment is terminated by a non-tab indented line. Multiple patterns, each to a line, may share the same comment.

Objective

Given the following directory structure:

tree
 .
 ├── fileA.txt
 ├── fileB.txt
 └── other_files
 └── fileC.txt

I would like to create a an info file(s) that would enable me to get the following output

 .
 ├── fileA.txt # Comments on file A read from info file
 ├── fileB.txt # Comments on file B read from info file
 └── other_files
 └── fileC.txt

Following the man pages this should be possible but I can't find an example how such an info file should be created. (削除) I've identified one potentially relevant discussion (削除ここまで)² but it's not clear to me what should be the structure of this .info file so tree can use it to populate outputs with additional comments.

² As discussed in the comments, the link is not pertinent to this question.

• Stéphane Chazelas: The one potentially relevant discussion is not relevant, it's about files with the .info extension which contain markup language for the info command.
• Konrad: @StéphaneChazelas I had a hunch that this may be the case; hence potentially. I will highlight this in the question.
• David Ongaro: You can find an extended example at fossies.org/linux/tree/doc/global_info. But what I'm more interested in is: is this .info file just an oddity of tree or are there other tools supporting it?

Answer 1

Example:

$ cat .info
a.jpg
 blah blah
 blih blih
*.jpg
 jpeg picture
$ tree --info
.
├── a.jpg
│  ⎧ blah blah
│  ⎩ blih blih
├── a.png
├── b.jpg
│  { jpeg picture
├── b.png
└── foo.user
0 directories, 5 files

(with a TAB preceding the comments per the manual you quoted).

Answer 2

Here's an example of the structure of the .info file for the tree command and how tree uses it: enter image description here

• terdon: Thanks for posting, but please don't post images of text since that cannot be copied from. We also can't understand the format since it's an image and shown using some fancy tool that adds formatting. Can you show the actual text in the file so others can copy it to reproduce your answer?
