This template is used for documenting country data meta-templates used by the flag template system.  The output of this template can be seen by directly viewing any of the templates in :বিষয়শ্রেণী:দেশের উপাত্ত টেমপ্লেট.  See উইকিপিডিয়া:উইকিপ্রকল্প পতাকা টেমপ্লেট for the main documentation and discussion page for the flag template system.  ব্যবহার This template is automatically invoked by the standard syntax of a country data template:  {{ {{{1<noinclude>|country showdata</noinclude>}}} | alias = Countryname | shortname alias = Shortcountryname  <!-- only necessary if Shortcountryname ≠ Countryname, otherwise omit --> | flag alias = Flag of Countryname.svg | size = {{{size|}}} | name = {{{name|}}} | variant = {{{variant|}}}  <!-- only necessary if there is one or more flag alias-variant parameters, otherwise omit --> }} The first parameter to a country data template is usually the name of a formatting meta-template. For example, টেমপ্লেট:পতাকা uses টেমপ্লেট:পতাকা/মূল to actually render the flag icon and wikilink. If the first parameter is missing, which is the case when a country data template is viewed directly, the template code fragment {{{1<noinclude>|country showdata</noinclude>}}} ensures that this template will be used as the default first parameter. This technique ensures that country data templates are "self-documenting" if they use the standard syntax.  অতিরিক্ত পরামিতি Many country data templates require additional documentation beyond the standard mandatory alias and flag alias parameters. This template will automatically document standard optional parameters (such as shortname alias) if present, and can document unique optional parameters (such as flag variants) if instructed to. This latter method uses documentation-specific parameters in the country data template to activate the additional output from this template. These documentation parameters are set off from the rest of the parameters in the country data template by a <noinclude> section: <noinclude> | var1 = ... | redir1 = ... | related1 = ... </noinclude>  পতাকার ধরন Flag variants are added to a country data template by the inclusion of one or more flag alias-label parameters, where each label is a unique identifier that is subsequently used as an input parameter to {{flag|...}}, {{flagicon|...}}, etc. To document these flag variants, use the varN documentation parameters to identify each label.  For example, টেমপ্লেট:দেশের উপাত্ত সিশেলেস identifies three flag variants (in addition to the current flag) with the following code: | flag alias-1976 = Flag of the Seychelles 1976.svg | flag alias-1977 = Flag of the Seychelles 1977.svg | flag alias-colonial = Government Ensign of the United Kingdom.svg These three variants are documented by the following code segment later in the template: <noinclude> | var1 = 1976 | var2 = 1977 | var3 = colonial ... </noinclude>  Up to forty flag variants can be documented by this method (using var1 to var40).  If more are present, these can be listed on a separate documentation subpage as described below.  Note that you do not have to use a varN parameter for the standard optional variant labels naval, air force and army (used for the country's naval, air force and army ensigns, respectively). If present, they will automatically be documented.  উপনামের পুনর্নির্দেশ Many country data templates have alias names that can be used instead of the usual country name with all of the main flag templates. These are usually, but not exclusively, standard country code abbreviations such as those specified in আইএসও ৩১৬৬-১ আলফা-৩ or by the আইওসি or ফিফা. These are implemented as redirects, and are listed in :বিষয়শ্রেণী:দেশের উপাত্ত পুনর্নির্দেশনা.  For example, বিষয়শ্রেণী:দেশের উপাত্ত DEU and বিষয়শ্রেণী:দেশের উপাত্ত GER both redirect to টেমপ্লেট:দেশের উপাত্ত জার্মানি, because DEU is the ISO code and GER is the IOC and FIFA code for Germany. Therefore, {{flagicon|DEU}}, {{flagicon|GER}}, and {{flagicon|Germany}} all have the same result. These redirect aliases are documented by the following template code fragment: <noinclude> ... | redir1 = DEU | redir2 = GER ... </noinclude>  Up to five flag redirects can be documented by this method (using redir1 to redir5).  সম্পর্কিত টেমপ্লেট Several country data templates are used for alternative forms to the common country data template for the nation, usually but not exclusively for historic nations. Pointers to these alternative templates are useful additions to the template documentation so that editors can use the correct template for their specific purposes.  For example, টেমপ্লেট:দেশের উপাত্ত সার্বিয়া ও মন্টিনিগ্রো includes the following code to document three other related country data templates: <noinclude> ... | related1 = Serbia | related2 = Montenegro | related3 = FR Yugoslavia ... </noinclude>  Up to six related flags can be documented by this method (using related1 to related6).  পতাকা নিবন্ধ লিংক This template shows a large flag image on the right of the documentation box, with a link to an article about the flag in the caption if it exists. The page that it evaluates is "Flag of ", with the value of  in the template code replacing . If there is an article about the flag even though "Flag of " does not exist, either create the latter as a redirect to the correct page or add the following parameter: <noinclude> ... | flag link = ''Article name'' ... </noinclude>  This can also be used to override the automatic link if "Flag of " does exist but leads to the wrong article.  অতিরিক্ত নথিপত্র For situations where the automatic documentation method is not completely adequate, additional documentation can be displayed by country showdata. Simply create a documentation subpage (named as টেমপ্লেট:দেশের উপাত্ত দেশের নাম/নথি) with the additional material, and it will be transcluded after all other output sections.  For example: টেমপ্লেট:দেশের উপাত্ত আয়ারল্যান্ড/নথি is used to explain why that template is distinct from টেমপ্লেট:দেশের উপাত্ত প্রজাতন্ত্রী আয়ারল্যান্ড টেমপ্লেট:দেশের উপাত্ত ফ্রান্স/নথি is used to document the list of country data templates available for each of the regions of France টেমপ্লেট:দেশের উপাত্ত মার্কিন যুক্তরাষ্ট্র/নথি is used to document the full set of flag variants (for each number of stars), and to list all of the country data templates available for state and territory flags  শ্রেণীবদ্ধকরণ This template automatically categorizes pages it is transcluded on in :বিষয়শ্রেণী:সমস্ত দেশের উপাত্ত টেমপ্লেট and in the tracking categories in :বিষয়শ্রেণী:দেশের উপাত্ত অনুসরণকরণ বিষয়শ্রেণী. Content categories, such as those by country or by type/status, should be added manually by putting them inside  tags on a template's documentation subpage. If a template does not have a documentation page yet, click on the "/doc" link at the bottom of the automatic documentation, add categories between the preloaded  tags and save the page.  The default sort key used for the automatic categories is the part after টেমপ্লেট:দেশের উপাত্ত in the page title. The parameter  can be used to specify a custom ASCII sorting key for these categories. For example, টেমপ্লেট:দেশের উপাত্ত অলান্দ দ্বীপপুঞ্জ and টেমপ্লেট:দেশের উপাত্ত প্রজাতন্ত্রী আয়ারল্যান্ড use this parameter to sort them under "A" and "I" respectively.  স্বয়ংক্রিয়ভাবে এই টেমপ্লেট দ্বারা যোগ করে:                  টেমপ্লেট বা নথিপত্রের পাতায় ব্যবহারকারীর দ্বারা যোগ করা হয়:
