 an URI to the archived version, the current date and time, title, description,

The database can be filtered by time, tags and full text and exported to CSV or

== FORMATS

=== csv

CSV is short for comma separated values. All fields are quoted and delimited by
commas. Line breaks in the full text are converted to "\n". Our CSV
implementation follows RFC 4180 and the full MIME media type is
`text/csv;charset=utf-8;header=present`.

=== asciidoc

AsciiDoc is a markup language that can be read as plain text or converted to
HTML, PDF and many other formats.

== SEARCH EXPRESSIONS

A search expression is either a single term, or several terms separated by _AND_
or _OR_. _AND_ takes precedence. The expression _Mountain AND Big OR Vegetable_
finds all things that have either Mountain and Big, or Vegetable in them. You can
use _||_ instead of _OR_ and _&&_ instead of _AND_. Note that *--search-tags*
only matches whole tags, Pill does not match Pillow.

== PROTOCOL SUPPORT

Since remwharead is built on libcurl, it supports the same protocols. See
*curl*(1), section _DESCRIPTION_. Titles and descriptions are currently only extracted
when using HTTP(S).

== ENVIRONMENT

You can use proxy servers with the same environment variables as curl. See
*curl*(1), section _ENVIRONMENT_.

== FILES

* *Database*: `${XDG_DATA_HOME}/remwharead/database.sqlite`

`${XDG_DATA_HOME}` is usually `~/.local/share`.
