The text of this GLEP was, to a significant extent, stolen from Python's  PEP-0012  by David Goodger and Barry A. Warsaw.
This GLEP provides a boilerplate or sample template for creating your own reStructuredText GLEPs. In conjunction with the content guidelines in GLEP 1 , this should make it easy for you to conform your own GLEPs to the format outlined below.
Note: if you are reading this GLEP via the web, you should first grab the text (reStructuredText) source of this GLEP in order to complete the steps below. DO NOT USE THE HTML FILE AS YOUR TEMPLATE!
To get the source of this (or any) GLEP, look at the top of the HTML page and click on the link titled "GLEP Source".
Provide adequate motivation here. In this particular case, we need to provide people with the information necessary to submit GLEPs in the proper form.
GLEP submissions come in a wide variety of forms, not all adhering to the format guidelines set forth below. Use this template, in conjunction with the format guidelines below, to ensure that your GLEP submission won't get automatically rejected because of form.
ReStructuredText is used to allow GLEP authors more functionality and expressivity, while maintaining easy readability in the source text. The processed HTML form makes the functionality accessible to readers: live hyperlinks, styled text, tables, images, and automatic tables of contents, among other advantages.
Not a problem for this GLEP. This section should be included even when it is only to state that there are no backwards compatibility issues.
How to Use This Template
To use this template you must first decide whether your GLEP is going to be an Informational or Standards Track GLEP. Most GLEPs are Standards Track because they propose new functionality for some aspect of Gentoo Linux. When in doubt, read GLEP 1 for details or contact the GLEP editors <firstname.lastname@example.org>.
Once you've decided which type of GLEP yours is going to be, follow the directions below.
Make a copy of this file (.rst file, not HTML!) and perform the following edits.
Replace the "GLEP: 2" header with "GLEP: 9999" since you don't yet have a GLEP number assignment.
Change the Title header to the title of your GLEP.
Change the Author header to include your name, and optionally your email address. Be sure to follow the format carefully: your name must appear first, and it must not be contained in parentheses. Your email address may appear second (or it can be omitted) and if it appears, it must appear in angle brackets.
For Standards Track GLEPs, change the Type header to "Standards Track".
For Informational GLEPs, change the Type header to "Informational".
Change the Status header to "Draft".
Reset the Version to "1".
Change the Created and Last-Modified headers to today's date. Be sure to follow the format carefully: it must be in ISO 8601 yyyy-mm-dd format, with the date represented in UTC (Coordinated Universal Time).
Reset the Post-History to empty for now; you'll add dates to this header each time you post your GLEP to email@example.com. If you posted your GLEP to the list on August 14, 2003 and September 3, 2003, the Post-History header would look like:
Post-History: 2003-08-14, 2003-09-03
You must manually add new dates (again, in UTC) and check them in. If you don't have check-in privileges, send your changes to the GLEP editors.
For Standards Track GLEPs, if your feature depends on the acceptance of some other currently in-development GLEP, add a Requires header right after the Type header. The value should be the GLEP number of the GLEP yours depends on. Don't add this header if your dependent feature is described in a Final GLEP.
Add a Replaces header if your GLEP obsoletes one or more earlier GLEPs. The value of this header is the numbers of the GLEPs that your new GLEP is replacing, separated by commas. Only add this header if the older GLEP is in "final" form, i.e. is either Accepted, Final, or Rejected. You aren't replacing an older open GLEP if you're submitting a competing idea.
Now write your Abstract, Rationale, and other content for your GLEP, replacing all of this gobbledygook with your own text. Be sure to adhere to the format guidelines below, specifically on the indentation requirements.
Update your References section. You should leave the Copyright section as-is, since all new GLEPs are to be licensed under the Creative Commons Attribution-ShareAlike 4.0 International License (CC-BY-SA-4.0).
Send your GLEP submission to the GLEP editors at firstname.lastname@example.org.
ReStructuredText GLEP Formatting Requirements
The following is a GLEP-specific summary of reStructuredText syntax. For the sake of simplicity and brevity, much detail is omitted. For more detail, see Resources below. Literal blocks (in which no markup processing is done) are used for examples throughout, to illustrate the plaintext markup.
You must adhere to the convention of adding two spaces at the end of every sentence. You should fill your paragraphs to column 70, but under no circumstances should your lines extend past column 79. If your code samples spill over column 79, you should rewrite them.
GLEP headings must begin in column zero and the initial letter of each word must be capitalized as in book titles. Acronyms should be in all capitals. Section titles must be adorned with an underline, a single repeated punctuation character, which begins in column zero and must extend at least as far as the right edge of the title text (4 characters minimum). First-level section titles are underlined with "=" (equals signs), second-level section titles with "-" (hyphens), and third-level section titles with "'" (single quotes or apostrophes). For example:
First-Level Title ================= Second-Level Title ------------------ Third-Level Title '''''''''''''''''
If there are more than three levels of sections in your GLEP, you may insert overline/underline-adorned titles for the first and second levels as follows:
============================ First-Level Title (optional) ============================ ----------------------------- Second-Level Title (optional) ----------------------------- Third-Level Title ================= Fourth-Level Title ------------------ Fifth-Level Title '''''''''''''''''
You shouldn't have more than five levels of sections in your GLEP. If you do, you should consider rewriting it.
You must use two blank lines between the last line of a section's body and the next section heading. If a subsection heading immediately follows a section heading, a single blank line in-between is sufficient.
The body of each section is not normally indented, although some constructs do use indentation, as described below. Blank lines are used to separate constructs.
Paragraphs are left-aligned text blocks separated by blank lines. Paragraphs are not indented unless they are part of an indented construct (such as a block quote or a list item).
Portions of text within paragraphs and other text blocks may be styled. For example:
Text may be marked as *emphasized* (single asterisk markup, typically shown in italics) or **strongly emphasized** (double asterisks, typically boldface). ``Inline literals`` (using double backquotes) are typically rendered in a monospaced typeface. No further markup recognition is done within the double backquotes, so they're safe for any kind of code snippets.
Block quotes consist of indented body elements. For example:
This is a paragraph. This is a block quote. A block quote may contain many paragraphs.
Block quotes are used to quote extended passages from other sources. Block quotes may be nested inside other body elements. Use a 4-space tab per indent level.
Literal blocks are used for code samples or preformatted ASCII art. To indicate a literal block, preface the indented text block with "::" (two colons). The literal block continues until the end of the indentation. Indent the text block by a tab. For example:
This is a typical paragraph. A literal block follows. :: for a in [5,4,3,2,1]: # this is program code, shown as-is print a print "it's..." # a literal block continues until the indentation ends
The paragraph containing only "::" will be completely removed from the output; no empty paragraph will remain. "::" is also recognized at the end of any paragraph. If immediately preceded by whitespace, both colons will be removed from the output. When text immediately precedes the "::", one colon will be removed from the output, leaving only one colon visible (i.e., "::" will be replaced by ":"). For example, one colon will remain visible here:
Paragraph:: Literal block
Bullet list items begin with one of "-", "*", or "+" (hyphen, asterisk, or plus sign), followed by whitespace and the list item body. List item bodies must be left-aligned and indented relative to the bullet; the text immediately after the bullet determines the indentation. For example:
This paragraph is followed by a list. * This is the first bullet list item. The blank line above the first list item is required; blank lines between list items (such as below this paragraph) are optional. * This is the first paragraph in the second item in the list. This is the second paragraph in the second item in the list. The blank line above this paragraph is required. The left edge of this paragraph lines up with the paragraph above, both indented relative to the bullet. - This is a sublist. The bullet lines up with the left edge of the text blocks above. A sublist is a new list so requires a blank line above and below. * This is the third item of the main list. This paragraph is not part of the list.
Enumerated (numbered) list items are similar, but use an enumerator instead of a bullet. Enumerators are numbers (1, 2, 3, ...), letters (A, B, C, ...; uppercase or lowercase), or Roman numerals (i, ii, iii, iv, ...; uppercase or lowercase), formatted with a period suffix ("1.", "2."), parentheses ("(1)", "(2)"), or a right-parenthesis suffix ("1)", "2)"). For example:
1. As with bullet list items, the left edge of paragraphs must align. 2. Each list item may contain multiple paragraphs, sublists, etc. This is the second paragraph of the second list item. a) Enumerated lists may be nested. b) Blank lines may be omitted between list items.
Definition lists are written like this:
what Definition lists associate a term with a definition. how The term is a one-line phrase, and the definition is one or more paragraphs or body elements, indented relative to the term.
Simple tables are easy and compact:
===== ===== ======= A B A and B ===== ===== ======= False False False True False False False True False True True True ===== ===== =======
There must be at least two columns in a table (to differentiate from section titles). Column spans use underlines of hyphens ("Inputs" spans the first two columns):
===== ===== ====== Inputs Output ------------ ------ A B A or B ===== ===== ====== False False False True False True False True True True True True ===== ===== ======
Text in a first-column cell starts a new row. No text in the first column indicates a continuation line; the rest of the cells may consist of multiple lines. For example:
===== ========================= col 1 col 2 ===== ========================= 1 Second column of row 1. 2 Second column of row 2. Second line of paragraph. 3 - Second column of row 3. - Second item in bullet list (row 3, column 2). ===== =========================
When referencing an external web page in the body of a GLEP, you should include the title of the page in the text, with either an inline hyperlink reference to the URL or a footnote reference (see Footnotes below). Do not include the URL in the body text of the GLEP.
Hyperlink references use backquotes and a trailing underscore to mark up the reference text; backquotes are optional if the reference text is a single word. For example:
In this paragraph, we refer to the `Python web site`_.
An explicit target provides the URL. Put targets in a References section at the end of the GLEP, or immediately after the reference. Hyperlink targets begin with two periods and a space (the "explicit markup start"), followed by a leading underscore, the reference text, a colon, and the URL (absolute or relative):
.. _Python web site: https://www.python.org/
The reference text and the target text must match (although the match is case-insensitive and ignores differences in whitespace). Note that the underscore trails the reference text but precedes the target text. If you think of the underscore as a right-pointing arrow, it points away from the reference and toward the target.
The same mechanism can be used for internal references. Every unique section title implicitly defines an internal hyperlink target. We can make a link to the Abstract section like this:
Here is a hyperlink reference to the `Abstract`_ section. The backquotes are optional since the reference text is a single word; we can also just write: Abstract_.
Footnotes containing the URLs from external targets will be generated automatically at the end of the References section of the GLEP, along with footnote references linking the reference text to the footnotes.
Footnote references consist of a left square bracket, a number, a right square bracket, and a trailing underscore:
This sentence ends with a footnote reference _.
Whitespace must precede the footnote reference. Leave a space between the footnote reference and the preceding word.
When referring to another GLEP, include the GLEP number in the body text, such as "GLEP 1". The title may optionally appear. Add a footnote reference following the title. For example:
Refer to GLEP 1 _ for more information.
Add a footnote that includes the GLEP's title and author. It may optionally include the explicit URL on a separate line, but only in the References section. Footnotes begin with ".. " (the explicit markup start), followed by the footnote marker (no underscores), followed by the footnote body. For example:
References ========== ..  GLEP 1, "GLEP Purpose and Guidelines", Goodyear, Warsaw, Hylton (https://www.gentoo.org/glep/glep-0001.html)
If you decide to provide an explicit URL for a GLEP, please use this as the URL template:
GLEP numbers in URLs must be padded with zeros from the left, so as to be exactly 4 characters wide, however GLEP numbers in the text are never padded.
During the course of developing your GLEP, you may have to add, remove, and rearrange footnote references, possibly resulting in mismatched references, obsolete footnotes, and confusion. Auto-numbered footnotes allow more freedom. Instead of a number, use a label of the form "#word", where "word" is a mnemonic consisting of alphanumerics plus internal hyphens, underscores, and periods (no whitespace or other characters are allowed). For example:
Refer to GLEP 1 [#GLEP-1]_ for more information. References ========== .. [#GLEP-1] GLEP 1, "GLEP Purpose and Guidelines", Goodyear https://www.gentoo.org/glep/glep-0001.html
Footnotes and footnote references will be numbered automatically, and the numbers will always match. Once a GLEP is finalized, auto-numbered labels should be replaced by numbers for simplicity.
If your GLEP contains a diagram, you may include it in the processed output using the "image" directive:
.. image:: diagram.png
Any browser-friendly graphics format is possible: .png, .jpeg, .gif, .tiff, etc.
Since this image will not be visible to readers of the GLEP in source text form, you should consider including a description or ASCII art alternative, using a comment (below).
reStructuredText uses backslashes ("\") to override the special meaning given to markup characters and get the literal characters themselves. To get a literal backslash, use an escaped backslash ("\\"). There are two contexts in which backslashes have no special meaning: literal blocks and inline literals (see Inline Markup above). In these contexts, no markup recognition is done, and a single backslash represents a literal backslash, without having to double up.
If you find that you need to use a backslash in your text, consider using inline literals or a literal block instead.
Habits to Avoid
Many programmers who are familiar with TeX often write quotation marks like this:
`single-quoted' or ``double-quoted''
Backquotes are significant in reStructuredText, so this practice should be avoided. For ordinary text, use ordinary 'single-quotes' or "double-quotes". For inline literal text (see Inline Markup above), use double-backquotes:
``literal text: in here, anything goes!``
Many other constructs and variations are possible. For more details about the reStructuredText markup, in increasing order of thoroughness, please see:
- A ReStructuredText Primer, a gentle introduction.
- Quick reStructuredText, a users' quick reference.
- reStructuredText Markup Specification, the final authority.
The processing of reStructuredText GLEPs is done using Docutils. If you have a question or require assistance with reStructuredText or Docutils, please post a message to the Docutils-Users mailing list. The Docutils project web site has more information.

A comment block is an indented block of arbitrary text immediately following an explicit markup start: two periods and whitespace. Leave the ".." on a line by itself to ensure that the comment is not misinterpreted as another explicit markup construct. Comments are not visible in the processed document. For the benefit of those reading your GLEP in source form, please consider including a descriptions of or ASCII art alternatives to any images you include. For example:
