+# ical
+
+iCalendar parser.
+
+Also usable as a command-line tool called `ical-org` to generate
+org-mode agenda files.
+
+## Usage
+
+    $ ical-org
+    ical-org: expected <input.ics> <output.org> [--base=YYYY-MM-DD (default: 1970-01-01)]
+
+## Install
+
+    $ stack install ical
+
+## Dev
+
+    $ git clone https://github.com/chrisdone/ical.git
+    $ cd ical
+    $ stack build
+    $ stack exec -- ical-org input.ics output.org
+
+## Typical use
+
+I've setup on my server a crontab that will run this command every 5
+minutes.
+
+Here is my crontab entry:
+
+    */5 * * * * sh /home/chris/gc-update
+
+Here is my `gc-update` script:
+
+``` sh
+mkdir -p /tmp/ical
+cd /tmp/ical
+
+wget https://calendar.google.com/calendar/ical/chrisdone%40gmail.com/private-<my code here>/basic.ics
+/home/chris/.local/bin/ical-org basic.ics basic.org --base=2015-06-01
+
+cp basic.org /home/chris/Dropbox/Org/gc.org
+
+rm -r /tmp/ical
+```
+
+My org-mode files are stored in Dropbox, so this update is replicated
+to my Dropbox which then my desktop computer will download only if
+there is any change.
+
+Open the file e.g. `gc.org` into an Emacs buffer and enable `M-x
+auto-revert-mode`.

+
+## Known issues
+
+I can't be bothered to resolve time zones yet. There is some work
+involved in reading them in, involving daylight savings time. For now
+everything is assumed to be UTC, but given that the main use-case,
+outputting org-mode files, only outputs dates, this is not a huge
+problem.
