+
+# NAME
+
+asn1c -- the ASN.1 Compiler
+
+# SYNOPSIS
+
+asn1c [**-E** [**-F**] | **-P** | **-R**] \
+      [**-S***dir*] [**-X**] \
+      [**-W***debug-*...] [**-f***option*] [**-gen-***option*] 
+      [**-pdu**={**all**|**auto**|*Type*}] \
+      [**-print-***option*] \
+      *input-filenames*...
+
+# DESCRIPTION
+
+asn1c compiles ASN.1 specifications into a set of
+target language (C/C++) encoders and decoders for BER, DER, PER, XER
+and other encoding rules.
+
+# OPTIONS
+
+## Stage Selection Options
+
+-E
+:   Run the parsing stage only. Print the reconstructed ASN.1 text.
+
+-F
+:   Used together with **-E**,
+    instructs the compiler to stop after the ASN.1 syntax
+    tree fixing stage and dump the reconstructed ASN.1 specification
+    to the standard output.
+
+-P
+:   Dump the compiled output to the standard output instead of creating the
+    target language files on disk.
+
+-R
+:   Restrict the compiler to generate only the ASN.1 tables,
+    omitting the usual support code.
+
+-S *directory*
+:   Use the specified directory with ASN.1 skeleton files.
+
+-X
+:   Generate an XML DTD schema for the specified ASN.1 files.
+
+## Warning Options
+
+-Werror
+:   Treat warnings as errors; abort if any warning is produced.
+
+-Wdebug-lexer
+:   Enable lexer debugging during the ASN.1 parsing stage.
+
+-Wdebug-fixer
+:   Enable ASN.1 syntax tree fixer debugging during the fixing stage.
+
+-Wdebug-compiler
+:   Enable debugging during the actual compile time.
+
+## Language Options
+
+-fbless-SIZE
+:   Allow `SIZE()` constraint for `INTEGER`, `ENUMERATED`,
+    and other types for which this constraint is normally prohibited
+    by the standard.
+    This is a violation of ASN.1 standard, and the compiler may
+    fail to produce a meaningful code.
+
+-fcompound-names
+:   Using this option prevents name collisions in the target source code
+    by using complex names for target language structures.
+    (Name collisions may occur if the ASN.1 module reuses the same identifiers
+    in multiple contexts).
+
+-findirect-choice
+:   When generating code for a `CHOICE` type, compile the `CHOICE` members
+    as indirect pointers instead of declaring them inline.
+    Consider using this option together with **-fno-include-deps**
+    to prevent circular references.
+
+-fincludes-quoted
+:   Refer to header files in `#include`s using **"**double**"** instead of **\<**angle**>** quotes.
+
+-fknown-extern-type=*name*
+:   Pretend the specified type is known.
+    The compiler will assume the target language source files
+    for the given type have been provided manually.
+
+-fline-refs
+:   Include ASN.1 module's line numbers in generated code comments.
+
+-fno-constraints
+:   Do not generate ASN.1 subtype constraint checking code.
+    This may make a shorter executable.
+
+-fno-include-deps
+:   Do not generate courtesy #include lines for non-critical type dependencies.
+    Helps prevent namespace collisions.
+
+-funnamed-unions
+:   Enable unnamed unions in the definitions of target language's structures.
+
+-fwide-types
+:   Use the unbounded size data types (`INTEGER_t`, `ENUMERATED_t`, `REAL_t`)
+    by default, instead of using the native machine's data types (long, double).
+
+## Codecs Generation Options
+
+-gen-PER
+:   Generate the Packed Encoding Rules (PER) support code.
+
+-pdu={all|auto|*Type*}
+:   Create a PDU table for specified types, or discover Protocol Data Units
+    automatically. In case of **-pdu=all**,
+    all ASN.1 types defined in all modules will form a PDU table.
+    In case of **-pdu=auto**, all types not referenced by any other type will
+    form a PDU table.
+    If *Type* is an ASN.1 type identifier, the identifier is added to
+    the generated PDU table.
+    The last form may be specified multiple times to add any number of PDUs.
+
+## Output Options
+
+-print-constraints
+:   When **-EF** options are also specified,
+    this option forces the compiler to explain its internal understanding
+    of subtype constraints.
+
+-print-lines
+:   Generate "`-- #line`" comments in **-E** output.

+

+unber dumps the output in the regular XML format which preserves most of the
+information from the underlying binary encoding.
+
+The XML opening tag format is as follows:
+
+<**tform** O="**off**" T="**tag**" TL="**t_len**" V="{Indefinite|**v_len**}" [A="**type**"] [**F**]>
+
+Where:
+
+**tform**
+:   Encoding form the value is in: primitive ("P") or constructed ("C") or constructed with indefinite length ("I")
+
+**off**
+:   Offset of the encoded element in the unber input stream.
+
+**tag**
+:   The tag class and value in human readable form.
+
+**t_len**
+:   The length of the TL (BER Tag and Length) encoding.
+
+**v_len**
+:   The length of the value (V, encoded by the L), may be "Indefinite".
+
+**type**
+:   Likely name of the underlying ASN.1 type (for UNIVERSAL tags).
+
+[**F**]
+:   Indicates that the value was reformatted (pretty-printed).
+This will never appear in the output produced using the **-p**
+command line option.
+
+## Example XML output:
+
+| \<I O="0" T="[UNIVERSAL 16]" TL="2" V="Indefinite" A="SEQUENCE">
+|  \<P O="2" T="[UNIVERSAL 19]" TL="2" V="2" A="PrintableString">US\</P>
+|   \<C O="6" T="[UNIVERSAL 16]" TL="2" V="6" A="SEQUENCE">
+|     \<P O="8" T="[UNIVERSAL 2]" TL="2" V="4" A="INTEGER" F>832970823\</P>
+|   \</C O="14" T="[UNIVERSAL 16]" A="SEQUENCE" L="8">
+| \</I O="14" T="[UNIVERSAL 0]" TL="2" L="16">
+
+# EXAMPLES
+
+Decode the given Tag/Length sequence specified in hexadecimal form:
+
+> unber\  **-t** "*bf 20*"
+
+Decode the DER file using two-spaces indentation:
+
+> unber\  **-i** *2*\   *filename.der*
+
+Decode the binary stream taken from the standard input:
+
+> cat *filename.der* | unber **-**
+
+Decode the binary stream and encode it back into an identical stream (see `enber`(1)):
+
+> cat *filename.der* | unber **-p** **-** | enber **-** > *filename.ber*
+
+# FOOTNOTES
+The constructed XML output is not necessarily well-formed.
+
+When indefinite length encoding is being used, the BER sequence which is not
+terminated with the end-of-content octets will cause the terminating **\</I>**
+XML tag to disappear.
+Thus, invalid BER framing directly causes invalid XML output.
+
+The `enber`(1) utility understands such XML correctly.
