-# synclib
-
-A small Go tool for creating symbolic links
-
-Created out of infuriating difficulty of creating symbolic links on windows
-
-## Instruction Formats
-
-The tool supports two formats for defining symbolic links:
-
-### 1. CSV Format (Legacy)
-
-Simple comma-separated values with the format: `<source>,<destination>[,force][,hard][,delete]`
-
-For example:
-```
-source_path,target_path
-source_path,target_path,true
-source_path,target_path,true,true
-source_path,target_path,true,true,true
-```
-
-Or with named flags:
-```
-source_path,target_path,force=true,hard=true,delete=true
-source_path,target_path,f=true,h=true,d=true
-```
-
-### 2. YAML Format (Recommended)
-
-A more readable format using YAML:
-
-```yaml
-links:
-  - source: ~/Documents/config.ini
-    target: ~/.config/app/config.ini
-    force: true
-  
-  - source: ~/Pictures
-    target: ~/Documents/Pictures
-    hard: true
-    force: true
-  
-  - source: ~/Scripts/script.sh
-    target: ~/bin/script.sh
-    delete: true
-```
-
-Alternatively, you can use an array directly:
-
-```yaml
-- source: ~/Documents/config.ini
-  target: ~/.config/app/config.ini
-  force: true
-
-- source: ~/Pictures
-  target: ~/Documents/Pictures
-  hard: true
-```
-
-## Input Methods
-
-The tool supports input of these instructions through:
-
-- Stdin
-  - `echo "this,that" | sync`
-- Run arguments
-  - `sync this,that foo,bar "foo 2","C:/bar"`
-- Files
-  - `sync -f <file>` (CSV format)
-  - `sync -f <file.yaml>` or `sync -f <file.yml>` (YAML format)
-  - Where the file contains instructions, one per line for CSV or structured YAML
-- Directories
-  - `sync -r <directory>`
-  - This mode will look for "sync", "sync.yaml", or "sync.yml" files recursively in directories and run their instructions
-
-## Options
-
-- `force: true` - Overwrite an existing symbolic link at the target location
-- `hard: true` - Create a hard link instead of a symbolic link
-- `delete: true` - Delete a non-symlink file at the target location (implies `force: true`)
-
-## Use case
-
-I have a lot of folders (documents, projects, configurations) backed up via Seafile and to have the software using those folders find them at their usual location I'm creating soft symbolic links from the seafile drive to their original location
-
-It would be problematic to have to redo all (or some part) of these symlinks when reinstalling the OS or having something somewhere explode (say software uninstalled) so I have all the instructions in sync files in individual folders in the seafile drive
-
-Which means I can easily back up my configuration and `sync -r ~/Seafile` to symlink it where it belongs
