+This command loads a TSV edges file into Graph-tool. Optionally, compute centrality metrics, and, optionally, dump the resulting graph-tool (.gt) object to disk. Prints the resulting edge file to stdout.
+
+## Usage
+```
+kgtk gt_loader [-h] [--directed] [--degrees] [--pagerank] [--hits]
+ [--log LOG_FILE] [-o OUTPUT]
+ filename
+```
+
+positional arguments:
+```
+ filename filename here
+```
+
+optional arguments:
+```
+ -h, --help show this help message and exit
+ --directed Is the graph directed or not?
+ --degrees Whether or not to compute degree distribution.
+ --pagerank Whether or not to compute PageRank centraility.
+ --hits Whether or not to compute HITS centraility.
+ --log LOG_FILE Log file for summarized statistics of the graph.
+ -o OUTPUT, --out OUTPUT
+ Graph tool file to dump the graph too - if empty, it
+ will not be saved.
+```
+
+## Examples
+
+Import a TSV file into Graph-tool, and compute degrees, pagerank and hits. We store the result to disk, and the statistics to log.txt.
+
+```
+kgtk gt_loader --directed --degrees --pagerank --hits --out file.gt --log log.txt ./data/conceptnet_first10.tsv
+```
