+
+## Reporting an issue
+
+Please do a search in [open issues](https://github.com/crazy-max/ghaction-import-gpg/issues?utf8=%E2%9C%93&q=) to see if the issue or feature request has already been filed.
+
+If you find your issue already exists, make relevant comments and add your [reaction](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments). Use a reaction in place of a "+1" comment.

+:+1: - upvote
+
+:-1: - downvote
+

+
+## Writing good bug reports and feature requests
+
+File a single issue per problem and feature request.
+
+* Do not enumerate multiple bugs or feature requests in the same issue.
+* Do not add your issue as a comment to an existing issue unless it's for the identical input. Many issues look similar, but have different causes.
+

+ * Additional options, for internal needs:
+ *
+ * - `chunkSize` - size of generated data chunks (16K by default)
+ * - `raw` (Boolean) - do raw deflate
+ * - `gzip` (Boolean) - create gzip wrapper
+ * - `to` (String) - if equal to 'string', then result will be "binary string"
+ * (each char code [0..255])
+ * - `header` (Object) - custom header for gzip
+ * - `text` (Boolean) - true if compressed data believed to be text
+ * - `time` (Number) - modification time, unix timestamp
+ * - `os` (Number) - operation system code
+ * - `extra` (Array) - array of bytes with extra data (max 65536)
+ * - `name` (String) - file name (binary string)

+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.

+ Entry assumptions:

+ strm.avail_in >= 6
+ strm.avail_out >= 258
+ start >= strm.avail_out
+ state.bits < 8
+
+ On return, state.mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm.avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm.avail_out >= 258 for each loop to avoid checking for
+ output space.

+ Process a set of code lengths to create a canonical Huffman code. The

+ symbols 0..codes-1. The Huffman code is generated by first sorting the
+ symbols by length from short to long, and retaining the symbol order
+ for codes with equal lengths. Then the code starts with all zero bits
+ for the first code of the shortest length, and the codes are integer
+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards
+ from their more natural integer increment ordering, and so when the
+ decoding tables are built in the large loop below, the integer codes
+ are incremented backwards.
+
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.
+
+ The codes are sorted by computing a count of codes for each length,
+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+
+ The length counts are used for other purposes as well, i.e. finding
+ the minimum and maximum length codes, determining if there are any
+ codes at all, checking for a valid set of lengths, and looking ahead
+ at length counts to determine sub-table sizes when building the
