+# g2e
+
+an opinionated gempub to epub converter written in awk.
+
+# usage
+
+an example (uncompressed) gpub file is provided.
+
+you can generate the corresponding epub file using:
+
+```
+make example
+```
+
+and then compress it with:
+
+```
+make epub
+```
+
+in order to convert another gpub, you can remix the following command, where `example-gpub/` would be the directory for your uncompressed gpub
+
+```
+awk -f g2e.awk example-gpub/
+```
+
+for the moment this only generates the epub metadata and table of contents files.
+
+# TODO
+
+* convert .gmi files to .xhtml
+* handle non-gmi files in the manifest
